itch-setup v1.26.0 linux errors but completes during setup, fails to launch

[saizai]

I ran https://itch.io/app/download?platform=linux per https://itch.io/docs/itch/installing/linux/ . See environment below and install logs attached.
itch-setup-log.txt
itch-setup-log-2024-04-25T11-47-53.062.txt

The install spat out a lot of errors but completed "successfully". Running ~/.itch/itch gave normal-looking CLI output (again see attached itch logs, and see below for output in other logs), and popped up a blank GUI window, which closed after a couple seconds. It does not seem to actually work at all other than that ~/.itch/itch-setup --uninstall does seem to work correctly.

N.b. I do have Chrome itself installed, and it runs fine.
