[5.0.0-rc1] 'Select preferred Language(s)' causes forgotten Server at app restart and whitescreen until resized

• This is not a troubleshooting question. Troubleshooting questions go here: http://www.mattermost.org/troubleshoot/.
• This doesn’t reproduce on web browsers (such as in Chrome). If it does, issue reports go to the Mattermost Server repository.
• I have read contributing guidelines.

Summary

with 5.0.0-rc1 the set servers (or all config) is forgotten when restarting the app

Environment

• Operating System: KUbuntu 20.04
• Mattermost Desktop App version: 5.0.0-rc1
• Mattermost Server version: 5.37.1

Steps to reproduce

• Have mattermost-desktop set up and successfully connected to your server (either with 5.0.0-rc1 or wit previous stable 4.7.2)
• restart mattermost-desktop
• be greeted with whitescreen and no server connected
• resize window to get the “connect to server” dialog

Expected behavior remember server over app restarts

Observed behavior forgetting server and having whitescreen

Whitescreen on restart

window after resizing showing “Add Server” dialog

nothing interesting in commandline output

$ mattermost-desktop 
08:34:23.392 › Current working directory is /home/nero, changing into /opt/Mattermost
08:34:23.702 › config.autostart has been configured: true
08:34:23.703 › config.autostart has been configured: true
08:34:23.786 › preloading with /opt/Mattermost/resources/app.asar/modalPreload.js
08:34:23.812 › config.autostart has been configured: true

I also tried to remove the .config/Mattermost folder, connected to the server, and restartet the app. Also forgot the server again

Possible fixes

@amyblais The only known issue is you might run into issues upgrading from one of the nightly 5.0 builds to 5.0-rc1. If you’re coming from v4.7, that should be working correctly.

@NeroBurner Does this reliably reproduce for you if you upgrade from v4.7.2 to v5.0-rc1?

[NeroBurner]

can confirm fixed with mattermost-desktop-5.0.0-rc2
