Same problem here, Fedora Silverblue 34.

I reverted to an older commit until this is fixed:

sudo flatpak update --commit=bd42be8a0bb96d4dbc217ed00453357c3d75d67eca49e37c68e144304be74c96 com.slack.Slack

[dkogias]

Same here on Fedora 33. I reverted to the most recent previous commit which works:

[maxamillion]

Thank you @ieugen! I did the same and the older commit works here as well on Fedora Silverblue 34

[ocosta]

Maybe it's not an option for everybody, but just for the record, the official (beta) RPM from Slack (v4.17.0) is working just fine on Fedora 34.

[johanfleury]

Slack user on Debian sid here, it works great until you try to send a file using Upload from your computer then it crashes with the same messages as reported above.

Same on Arch Linux 😢

Last update (commit : 50d5078ac08828a2a6fc7eaa3e614a49f0d3f7495d8fddacbe1f264c1024964c) solved the issue for me.

I confirm.

[Eonfge]

Hey all, sorry for missing you in the conversation. I quickly escalated the issue when I had the same problem this afternoon:

https://github.com/flathub/com.slack.Slack/issues/131

@barthalion Could quickly help me but it seems that this application is in need of some more help. If any can help, then that will be much appreciated. Most of this package's management is currently on auto-pilot so if you can, feel free to get a merge-request in there to help the project.

Also, don't forget to encourage Slack in supporting Flathub directly ;)

[vchernin]

This issue also doesn't occur for me with the latest updates on Fedora 34 Silverblue, the app starts as expected. Should this issue be closed now?

Indeed, upgrading to the latest version fixed the issue.
