File won't Open, Unknown Error Message

Hey Guys,

yesterday I was working on my project when I got stuck on the logic for the loopwhile node.
Searching for a solution I looked at the example file in the dictionary (Dynamo Dictionary).
Immediatly I saw my mistake and wanted to open my project file when nothing happend. Opening it from an already open file produced no reaction at all.
Opening from the main menu resulted in this error message:

I navigated to my backup files, but the backup has the same problem.
I couldn’t find any other post about that error message and frankly it goes directly over my head to fix it myself.

Since I am a new user here I can’t attach files, are there any pointers as to what I can do to troubleshoot this myself?
The time between working in my project file and returning to it were 5min at max.
Today with a freshly booted system I tried opening it again, no luck, still the same Error message as above.

I am using this Dynamoversion in Revit 2023:
Dynamo Core 2.13.1.3887
Dynamo Revit 2.13.1.3891
Underneath it says Up-to-date

The file contains nodes from the Sofistik Bridge + Infrastructur Modeler

Thanks for any help

Richard

Ok, found the solution:

this works even tho I got a completely different error message.

had the same problem yesterday. For my case it happened because I modified some nodes in the MEPover package as it was written in ironpython2 and I needed it to work in Cpython3
