System Information
Operating system: Linux-4.19.0-9-amd64-x86_64-with-debian-10.4 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.113

Blender Version
Broken: version: 2.83.5, branch: master, commit date: 2020-08-19 06:07, hash: c2b144df39
Worked: Not sure, possibly 2.82a

Short description of error
When using sculpt mode, the Dyntopo menu will fail to display after using the Box Hide brush. The Dyntopo information cannot be seen either in the drop-down (top of screen) or in the Active Tool Menu (right side of screen). I only have officially supported / included addons enabled, e.g. LoopTools, F2, BoolTool, etc.

Exact steps for others to reproduce the error

Open the attached blend file (garbage4-begin-sculpt.blend)garbage4-begin-sculpt.blend
Select the mesh for the character's head
Optional - in object mode apply scale with CTRL+A
Tab into Sculpt Mode
Click the Dyntopo drop-down. You will notice it works normally
Enable Dyntopo with the checkbox
Choose the Box Hide brush
Hide a section of the head mesh using the Box Hide brush
Click the Dyntopo drop-down. Notice it no longer works. (see attachments)
Click the Dyntopo settings in the Active Tool Menu and notice that they are empty even when expanded. (see attachments)
Look in your terminal, and you will notice that the Python traceback:

File "/home/user/pathto/blender-2.83.5-linux64/2.83/scripts/startup/bl_ui/space_view3d_toolbar.py", line 822, in draw

This is fixed by e233ee1c1f

It only is in 2.90 and 2.91, so you can get a build from https://builder.blender.org/download/ with this working.

@Jeroen-Bakker: Dont think this is critical enough to be backported to 2.83 LTS? (or maybe it it, will let you decide...)

Sent request in PM (this is preffered by @Jeroen-Bakker) and I will close this report, as bug was resolved.

Even though there won't be too many of these requests, I don't think it is worth to keep these reports open.

@iss I don't quite understand why this was closed as Invalid . Can I get some clarification on what this means for Blender 2.83 LTS? Is the fix from 2.90 going to be backported to 2.83?

@brendenahyde : This was already committed to the LTS branch, see d80a95c2ee, so it will be available in 2.83.6

This is expected though, tools that dont have a brush cannot use Dyntopo, what is wrong with that? Only other thing I could imagine here would be to grey things out (make inactive), but still, nothing would show here since we dont have a brush with settings, might as well hide the whole thing, no?
