Similar to, but *not* a duplicate of:

... which seems to be fixed by updating Mono using their PPA.

Interesting that this seems to be a separate issue from the other Mono-related crashes.
Are there any specific actions that trigger this, or is it random like the other bug?

On Ubuntu 18.04 I updated Mono to the latest version. Command: mono -V
returns:
Mono JIT compiler version 6.10.0.104 (tarball Fri Jun 26 19:38:24 UTC 2020)

Can you please retest if this by any chance is fixed on newest Mono.

just tried the solution here:

and it worked, although it is a 350MB download.

Mono version now reads:

The only differences I noticed is mono version downgraded from 105 to 104 and LLVM is now enable.

I have the same mono version, after the same update on the same platform (20.04), but I'm still getting the same crashes.

Ok, I ran some other pending upgrades (`sudo apt upgrade`), restarted my computer, and Pinta has stopped crashing.
