11/19/2025, 5:24 PMI’ve encountered a reproducible crash in Blender 5.0 which appears to be caused by ZenUV.
The crash happens when launching Blender from the Windows console.
Blender seems to crash while ZenUV attempts to draw gizmo UI during a depsgraph update at startup.
When ZenUV is removed or disabled, Blender starts normally from the console and render commands work with no errors.
Relevant part of the crash log:
...
# Python backtrace
File "C:\Users\....\AppData\Roaming\Blender Foundation\Blender\5.0\extensions\user_default\ZenUV\ui\gizmo_draw.py", line 232 in zenuv_depsgraph_ui_update
Thank you!

11/19/2025, 5:55 PMIf you are not afraid of Python, I would like to offer to completely disable depsgraph in a background
