Hello,
I have an interesting problem…
I was finicking with a custom node to log usage in graphs.
When i ran my graph in Revit 2022, my Revit 2021 session crashed. I didnt think much of it, until it happened in Revit 2023 aswell. this made Revit 2022 crash…
I have added the log below:
journal.0055.txt (3.4 MB)
Do you have an idea what is happening here @JacobSmall
Looks like an issue with the node itself, not really a problem with Dynamo. How are you recording the log?
This log was just the standard log you get when Revit crashes.
I think the problem occured when i tried to run the graph with the node, which contained python 2.7, which wasnt installed…
Still not sure how it manages to crash a revit version its not even running the dynamo graph in…
Sorry - should have been more specific.
How are you logging use with your node? My guess is there is a conflicting process being force closed which is causing the WPF collapse in the other Dynamo and Revit.
What’s in the Python nodes?
Slightly cleaner method here in an updated video vs my older one, see how it goes:
For some reason, after i added this node, my graph gets rather unstable… (it’s a very large graph to be fair…)
Oh i can’t believe i missed that video!
Thank you, i’ll give this a go, love your videos! 
I’ve also packaged the code up in a custom node in Crumple, dubbed as the ‘logger’.
If adding this was the route cause, it might be the issue. I can see how it may be causing some issues with concurrent RevitDynamoModel instances.
A few things to try:
