I have encountered a similar issue on downgrade of snap package and workaround does work. Previously had chromium 94 installed. Due to issues with top-bar rendering downgraded chromium to version 93. Got issues with any attempt to upload/download file. Running:
rm ~/snap/chromium/current/.last_revision fixed the issue -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863801 Title: [snap] After deleting the cache, chromium crashes when file picker is called to upload files or folders To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1863801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
