Crash in paperspace - 2021 SP1

I am having an issue where the drawing will crash in paperspace - this seems to be happening when panning around a drawing. Crashes are very frequent, every few minutes. I have tried the following without resolution:

1. Clean install of draftsight
2. Clean install and update of graphics drivers to latest version
3. Disable / Enable display adaptors

I've also noted that lineweight isnt correctly displaying in modelspace - lwdisplay is on

Is it possible to roll back to a previous version of draftsight as this error is making workflow near impossible.

Thanks for your help
