Hi everyone,
Today I started having an issue with Slack Flatpak app.
Indeed , it started crashing when trying to open it by clicking on the icon, accessing to the app through web-browser redirection or starting from CLI is working instead…
So I have no idea what the issue can possibly be and I request some help from contributors please.
Feel free to ask for more informations or necessary logs.
Thanks.
Please try starting the app from the terminal and attatch that log.
flatpak run com.slack.Slack
@GOGI Can you provide information on the distribution you’re using, and your hardware?
Clicking on the icon in the taskbar is working fine here for me.
gogi@fedora:~$ flatpak --user run com.slack.Slack

And the app is working fine here when launched through terminal like you mentioned?
@GOGI Can you provide information on the distribution you’re using, and your hardware?
Yep, it was working for me too until an hour ago, and I didn’t change anything to my config, neither did I any system upgrade…
I’m running a Fedora Workstation on an older Sony Vaio laptop.
Yep, running it this way from CLI is running fine, as well as running it trough web-browser redirection from my slack account…
That’s why I don’t understand what’s the issue here…
EDIT : I already tried to clear cache eventually, but that didn’t help.
Can you try unpinning and repinning the icon on the taskbar you’re trying to click?
The icon isn’t pinned to my taskbar, I go and pick it up in the Gnome apps menu when needed. 
Too much icons already on my dash
Can you launch the app if you open the app drawer with the super key, then start typing “Slack”, and click on the entry that pops up?
Same behaviour, starts opening then crashes…
I also just had a look at the log, after trying to open the app the three ways I mentionned before, the log output is exactly the same for all three ways. No difference that could lead me to a point unfortunately.
