The issue you are facing:
Once I try to open the desktop app, it is not opening. I have the little symbol in the task bar, but nothing happens. When I move the cursor over the sympol, my username and domain appears among some other data.

I uninstalled, let ccleaner run, installed again. Same problem. And my username and domain appears again in the tool tip when moving the cursor over the symbol. I would like to completely delete all the data from the nextcloud desktop app and reinstall it, but nextcloud seems to store some data also after I uninstalled. how can I delete this data?

Is this the first time you’ve seen this error? (Y/N):

Steps to replicate it:

The output of your Nextcloud log in Admin > Logging:


The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):


The output of your Apache/nginx/system log in /var/log/____:


I solved the problem.

Nextcloud desktop app was not working as Windows defender activated folder protection and therefore the folder “documents” was read-only.

I have the problem again. It should be possible to delete all the data from nextcloud when uninstalling.

Can anyone let me know how I can completely delete all data from nextcloud with the uninstall the desktop client?
