Welcome to TVPaint Community forums !

Making a note here of a couple of issues I have encountered that are causing TVpaint to abruptly exit while working:

- Occasionally using the delete key to delete a layer crashes / exits program (always works fine with dedicated delete layer button)
- Application consistently quits if attempting to copy and paste a layer group into a new clip / scene

I am avoiding doing either of these actions right now to prevent work loss but wanted to log them somewhere in case others experience the same problems.

- Occasionally using the delete key to delete a layer crashes / exits program (always works fine with dedicated delete layer button)

Are you referring in the bolded portion I quoted to the "delete" option if you right click on the layer? Just asking because I have had several crashes while doing that, but it is not all the time for me and I have been unable to reproduce it consistently to figure out what circumstances cause it.

Also, is your delete key set to "Tvpaint Animation > delete selection (adaptive)?" I have had crashes with using this shortcut as well, but also intermittently.
