The file chooser dialog in ANY website in any browser (Firefox, Brave, Vivaldi) doesn't appear when I click on the upload button:

unclear if it's related, but I have the same issue for many flatpaks: pop-os/cosmic-epoch#1331 (and some related / duplicates: https://github.com/search?q=repo%3Apop-os%2Fcosmic-epoch+file+picker&type=issues)

From the logs it's happening in this a11y function. @nuke-web3 maybe try the suggestion from #121 and see if it fixes the issue for you.
