Graphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.86

Blender Version
Broken: version: 3.1.0 Alpha, branch: master, commit date: 2022-01-03 17:16, hash: b7ad58b945
Worked: didn't crash but showed an error message in 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: 5be9ef4177

Short description of error
Mode locked and crash if objects become disabled in viewport while not in object mode (fixed in 3.6, 3.3 LTS issue only)

Exact steps for others to reproduce the error

add a shapekey to the default cube
enter sculptmode
disable the cube in the viewport using the outliner as above
move mouse cursor to 3D view port, then Blender crashes

Original report

Short description of error
Objects that are in a mode which is not Edit Mode nor Object Mode, will lock the mode setting (so the mode options are greyed out and unusable) if they get disabled in the viewport. Hiding will not cause the this bug, it needs to be disabled in viewport using that display icon in the outliner, not the eye.

The solution for this is probably to make the disable in viewport action switch the mode to object mode if the active objects gets removed (much like delete from outliner). Another solution would be to still allow the mode switch.

Much worse though! Blender crashes sometimes when it gets into this state. I can reliably crash blender as described below.

Exact steps for others to reproduce the error
Go into weightpaint mode of the default cube and disable it in the viewport using the outliner (you need to enable the option first). Now you are stuck and have to enable it in the viewport first to be able to edit anything.

Now restart blender etc. and try this:

Go into Vertex Paint Mode of the default cube
Hit Tab to go into Edit Mode
Disable the cube in the viewport using the outliner as above
Hit Tab to switch out of Edit Mode -> Crash

I am the person who reported this glitch, it is said that it's solved, but it still happens in latest Blender version 3.2.2. Please check it again.

When object has at least one shape key, same glitch happens.
For example there is a cube, and it has a shape key and I select this cube and activate sculpt mode and hide it using "Disable in Viewports" after that move mouse cursor to 3D view port, then Blender crashes.

I checked crash log and it says

Exception Record:
