Nextcloud version (eg, 20.0.5): latest, downloaded from website today
Operating system and version: Windows 11
The issue you are facing:
After setting up server, app began putting temp files in folder, but nothing else. Whenever I try opening the app, I either get to see nothing at all, or the notification popup bottom right of the screen.
All I did was download the app from nextcloud.com, then run the installer again to repair, uninstalled, reinstalled, rebooted, etc.
My laptop runs fine otherwise. I use MS Defender and added nextcloud folder as an exclusion after seeing it didn’t work, but that didn’t help.
I can’t find the log, not a config file under C:\Program Files\Nextcloud.
