System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.92

Blender Version
Broken: version: 2.90.0, branch: master, commit date: 2020-08-31 11:26, hash: 0330d1af29
Worked: 2.83.5
Caused by 3ebe97c06b

Short description of error
Hello,
I think I found a very anoying bug here. with this mesh, as soon I go in weight paint mode, a part of my mesh is locked and become uneditable and you cannot select some vetices of the mesh in edit mode. I tried with the 2.83.5 version and it seems to work as intended with this one. the issue only comes with 2.90.0 here.

here is the .blend file: bug isolation 2.90.0.blend

Exact steps for others to reproduce the error

Open the attached .blend file
at this point all vertices are still selectable
enter weight paint mode
go back to edit mode
and here you end with a glitched mesh (vertices dont draw, cannot be selected, alt+ H to makes them visible again)

Exact steps for others to reproduce the error (another symptom: sculptmode to edit mode automatically hide certain vertex)

Create a cube,
Delete a face,
Extrude some vertex,
Enter in sculpt mode,
Enter in edit mode.
Extruded vertex will be hidden (alt+ H to makes them visible again)

I hope someone will find what's going on.

thank you for your time

Yes!
Thank you Philipp, I managed to fix my problem with this manipulation:

go to sculpt mode
hit alt-H to unhide everything
and then all is back to normal in edit mode
still not sure if it's a bug or a mishandling

OK, that is good to here.

I havent investigated this further (and from quick look this doesnt seem to happen every time you hide facesets in sculptmode), so might be something specific to this file.
Will lower the prio.

@PabloDobarro will you have a look here?

Philipp Oeser changed title from ~~Weight paint mode freeze a part of the mesh in Edit mode~~ to Mode switching hides vertices in Edit mode (Weight paint / Sculpt mode --> Edit mode)
