This is on Linux Mint 20.

Unfortunately we do not currently support Linux Mint 20 (which is approximately equivalent to Ubuntu 20); this component needs at least Ubuntu 22. You can read more and comment/upvote here:

Although it won't fix your problem, it's also the case that we should show a more informative error here. I've written that up as well:
