Every time I try to use network manager widget to connect to new network it entire plasma shell crashes. Connecting to the network using manager window (which requires to add connection and input router's mac address manually) works. After connection is saved you can connect to the network without issues. I checked it on two different machines, it works the same for both. Another issue is that while I have one network seleted on the list and networks position changes my selection stays with the posision and not the network, so at the end I cna't tell which network system is traying to connect. STEPS TO REPRODUCE 1. open network manager widget 2. find new network you have never connected to before 3. select it (you can notice that if it changes position on the list, you might end up with different network then one you have selected) 4. click connect and input password (still it is possible that networks will swap places, so you might be inputing password for wrong network) 5. click connect one more time 6. wait until plasma is done restarting itself after crach OBSERVED RESULT Networks changing places but selection stays on same position, resulting in changing which network is selected. Note that this may result in sending your password to wrong network which is searious seutiry issue (someone will recieve your wifi password) Plasma crashes when you try to connect EXPECTED RESULT List shouldn't update when you have a network selected, not to mention when you are inputing password. New connection should be establiched and you should be connected to it SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 20.10 (available in About System) KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION I know I am describing two issues there, but I think they might be connected, since I was unable to finninsh proedure without being interrupted by list items changing places, so I can't be sure if crash will occur if that doesn't happend.
Crashes should have a backtrace. See the sad face icon in the system tray when it restarts. >Note that this may result in sending your password to wrong network which is searious seutiry issue (someone will recieve your wifi password) Fortunately they won't, that's not how WPA handshakes work. If it did you could intercept any password just by spoofing as SSID.

There was no backtrace (unless it's in some file know nothing about). No sad face icon was displayed. Just panels were gone for 2-3 seconds. I tried doing it again (removed connection, then tried to add it again) At first try it crashed (but still no sad face icon was displayed). Second time it suddenly worked (1/7).

Ok. After several (more than several) tries, finally I've got a sad-face icon.

New information was added with comment 5; changing status for inspection.
I don't see anything plasma-nm related in the backtrace. Can you install debug symbols for plasma-framework and for kdeclarative and get a new backtrace?
It means the crash is in kdeclaratives's plotter, which has been replaced in newer plasma-nm
Oh, right, that's most likely the issue. Closing this bug now then.
