Android Tablet crashes when using local adjustment tools

I am testing on a Galaxy Tab S3 and not seeing any issues.

Brush, Graduated and Select Subject Masks all work with no crash. 

Android 9.0 

Lr 7.0.0

Have you installed the update?

Version Lightroom (Android): 7:0:0

Version Android: 11

Opening the brush tool crashes LR on my Galaxy Tab S7 Plus. Is this something in the pipeline to fix or not?

I have rolled back to version 6:4:0 via a 3rd party website as various other things also caused crashes, making LR 7 unuseable. My device is quite powerful and modern, so this shouldn't be happening. I don't seem to be able to find any support or answers anywhere.
