I have pretty much the same problems on Linux, so I don't think it's an OS issue. Inkscape is one of those tools that I use often, and am very grateful for, but I usually find the actual experience of using it very painful. Regular crashes being one of the big pain points at the moment.

What distro? I use Fedora, and I use it all the time and have never had it crash.

Both Ubuntu and Pop. In fairness, I think I've got it installed on Pop via Flatpak, which is sometimes part of the problem, but that's not the case on Ubuntu.
