Hi all,
Searched the archives, but couldn’t get something matching my symptoms.
This is with Revit 2021, but I can’t pull the Dynamo version running under it, due to the issue at hand.
There’s a second window popping when I start Dynamo, but I can never bring it in front or view it at all. I can shut it down though. I don’t seem to see a process in Task Manager.
Thank you!
Hi @Ra-X ,
Could you maybe share a screen recording of some kind so we can also see what you are seeing?
Restart the CPU, open Revit, start a new project from no template, launch Dynamo to reproduce the issue, quit Revit, and post that journal from that session with the screencast.
I was just heading in that direction - I started looking at journals with our template used for a project, but switched as per your request.
Enclosed.

Well, I seem to be a “new user,” so I can’t upload anything…
Anything I can possibly look at while that aspect gets sorted out?
Thank you.
Try now. Used some of my magical moderator powers to bump you (you were fairly close before - entering more topics while logged in and you’d already be there).
Sorry you can’t see my cursor/pointer… Something about Camtasia saving to avi. After starting Dynamo, it starts thinking, and then the Dynamo window gets behind Revit’s and stays there in the upside down 
Well… I have some good news and some bad news. But first up thanks for proving this info as you did - precisely what was needed and executed to perfection (missing mouse isn’t an issue).
The bad news is that the exact issue isn’t clear. But the good news is that we have a LOT of other issues (I estimate around 40) to address which may resolve the problem.
If you search the journal for “API_ERROR” you’ll see there are 49 flags, most of which (all?) are around DLL conflicts. Any one of these could be causing this issue or more. You’ll also notice a few references to “Log4Net” which hopefully triggers a few ‘on no’ thoughts, as Revit should be fully patched by now.
To address these issues, I recommend disabling all add-ins and seeing if the issue persists. If not, add them back via a binary search or in segments until you identify the culprit(s). Note that some of the add-ins you’re using a rather deeply rooted, so it make take a few reviews outside of the standard add-ins folder.
If that doesn’t resolve the issue, attempting to reset your Dynamo user preferences could resolve the issue. However the above should be addressed if it’s a root cause or not, and the settings should migrate between builds on the same system, so I’m hesitant to type that ‘how to’ up as it would likely make more work for you if the other issue isn’t addressed first. Give the add-in removal a shot first and let me know how that goes, and we can take next steps from there.
Hi Jacob,
Some updates on this, though no breakthrough yet.
More data on this:
I was able to start Dynamo under Revit 2021 again (it’s a toss up if it works). This time I got a warning, which may be the key to these issues.
Here’s the log:
System.IO.FileLoadException
Dynamo has detected a conflict with a dependency and may be unstable. If any issues are detected, please uninstall addins or packages and contact the provider.
While loading assembly RhythmRevit2022, Version=2021.12.1.0, Culture=neutral, PublicKeyToken=null, Dynamo detected that the dependency RevitAPI, Version=22.0.0.0, Culture=neutral, PublicKeyToken=null was already loaded with an incompatiable version. It is likely that another Revit Addin has loaded this assembly, please try uninstalling other Addins, and starting Dynamo again. Dynamo may be unstable in this state.

@Ra-X … I might be completely wrong, but looking only at your posted video, I had a similar problem which was solved by right-clicking on the Dynamo icon (brought up by hovering over the Revit icon) on the task bar, and select ‘Maximise’. This seemed to bring Dynamo out from wherever it was hiding.
Hi Scott,
And thank you for your note.
When this happens - and I’ve seen it happen before also with actual Revit AddIns - no regular Windows operations will bring that window from “behind” the Revit window. Will give it another try (triple check!) next time I see this - though right now they all work (with a varying number of “System.IO.FileLoadException” notifications) and hopefully they stay working…
Thank you again!
Start by disabling all of your add-ins. One of them is causing a conflict.
Jacob,
I did - see my post #9 above (Dynamo fails to start (Revit 2021) - #9 by Ra-X), to no avail. I used AddInnManager.exe - would this make a difference, maybe?
Thank you.
The System IO exception above indicates a few were active. Disable them all and post a Revit journal and Dynamo log file after recreating the issue
I’m having a similar prob. Revit crashes when I open Dynamo. My symptoms started when I tried two Revit plugins Bird and Orkestra. I uninstalled both and they somehow corrupted my files causing Dynamo’s package manager to disable. After finally doing a clean uninstall of 2021 and 2022, then reinstalling Revit 2021.1.7 (latest) Dynamo and Revit now crash (together at the same time) a few seconds after I open a new project and then Dynamo. I don’t have to do anything. After a few seconds it crashes. Here is the Revit journal file. Any idea what “Exception occurred” means? Also i’m not sure why the timestamp of Dynamo is the next day May 19 when today is still May 18.
