I found a workaround after seeing the commit.
- go to your “[blender installation folder]\3.5\scripts\startup\bl_ui”
- open the init.py file
- go to line 149
- change “alpha” to “release” (or “rc” / “beta” if you used that build)
I don’t know if it’s the right way to reverse it, i’m not a coder, but at least now i can access the testing folder.
hope that helps
