Ubuntu 22.04: Both eye of gnome and gimp failing with undefined symbol error

Since a few days both eog and gimp fail when launched from the command line. I get the same error message from both:

gimp: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATEeog: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

This happens in all of the default terminal, x-terminal, and terminator. Snap says all packages are up to date. I'm at my wit's end. What else should I look at?

Thanks!

EDIT: gimp and eog aren't snap apps. Here is what snap list yields:
