***
Dolphin becomes unusable (freezing all the time), after using SMB once.
I've connected to my local NAS (smb://192.168.1.60/xx) while being on VPN with home network,
Now i'm disconnected, and Krusader is freezing/hanging all the time (i believe it's because that SMB resource I accessed previously).
even after killing it and restarting, it freezes at start (not showing proper window content).
***

SUMMARY


STEPS TO REPRODUCE
1. connect to your home VPN (wireguard)
2. access home server resources with Dolphin, ex. smb://192.168.1.60/xx
3. stop accessing home server resources (browse some local PC folders)
4. disconnect from home VPN
5. try to browse local folders - Dolphin freezes, restart doesn't help.

OBSERVED RESULT
Freezing/hanging most of the time, on any action, even after Dolphin restart and not accessing SMB resources anymore, the app is unresponsive and unusable.

EXPECTED RESULT
Normal work, without freezing

Thanks for the bug report.Unfortunately, Plasma 5.27 is very old and out of support from KDE at this point.

I would suggest you report this to Ubuntu, they're the ones who bear the responsibility of maintaining the older software they ship with their LTS releases. Unfortunately KDE itself cannot provide support for very old Plasma versions anymore.

You can report the bug through https://help.ubuntu.com/community/ReportingBugs

Thanks for your understanding.
