Windows 10 client always crashes after some time

[tflidd]

I think that is something that can directly go on the bugtracker Issues · nextcloud/desktop · GitHub

and start your client with logging enabled next time, so you get some additional logs: https://docs.nextcloud.com/desktop/3.0/troubleshooting.html#saving-files-directly

There was also a similar issue with previous versions where two config folders were on the system (but it failed directly at start):

Nextcloud client crashes at startup on Windows 10

I confirm what said @Benoit I deleted this folders: C:\Users\yourname\AppData\Local\Nextcloud C:\Users\yourname\AppData\Roaming\Nextcloud Then, I reinstall 3.0.1 version, now it works after a reboot.
