Error creating stack

[sergeykahn]

✈ Pre-Flight checks

• I don't have SentinelOne antivirus installed (see above for the solution)
• I have searched in the issues (open and closed) but couldn't find a similar issue
• I have searched in the pyRevit Forum for similar issues
• I already followed the installation troubleshooting guide thoroughly
• I am using the latest pyRevit Version

🐞 Describe the bug

One of our office computer's gets the following message when opening Revit (confirmed both Revit 2024 and 2023 versions). We tried uninstalling and reinstalling pyRevit, but that didn't work. The rest of the computers are all running the same build of Revit and pyRevit but don't have this error.

Additional context

We have custom pyRevit extension that is used by the office. When one of the pushbuttons from the extension are pressed and then canceled out, Revit crashes. This only happens on the problem computer, while the other computers handle the extension without issue.

Start by removing the custom extensions search path
It should work.
I think one of your extension .stack folder is malformed as the message says, 2 to 3 pushbutton per stack top.
Re enable your custom extensions path

Regarding the button that crashes upon exit, we would need the complete pushbutton folder to test it

[sanzoghenzo]

From your previous output we could't see the installed pyrevit version, one of the Registered Clones section should list the path to the pyRevit folder.

What version did you install and how (normal admin installer or via CLI)?
