Error that pops-up and crashed the model

[aabdelrahman6GQRX]

Hi,

I'm currently working on a project that uses cloud-shared Revit model (Revit 2021 version). Almost everyday while I'm working, the error message shown below pops-up and Revit crashes without letting me save/synchronize my work:

Does anyone know what are the possible reasons for this? and how this problem can be eliminated?

Thanks in Advance,

Ahmed

Do you have all of the hotfixes and updates for Revit 2021 installed? I often see this resolved when Revit is updated. I may also be wise to update your graphics driver if it is significantly out of date as well.

This may be the same thing? I had the same issues in a sprinkler-modell in R2021. Got better after a lot of general cleaning up and file maintenance. But never really cleared it it completly. I suspected some sort of hidden geometry messing up the rendering of the view. Would happen in 3d views when scrolling/zooming.  https://knowledge.autodesk.com/support/revit/troubleshooting/caas/sfdcarticles/sfdcarticles/An-unrec...
