Bug description

I use the Win11 system, with at least 3 computers synchronized. However, when switching computers, the client gets stuck during synchronization and then exits without any prompt. If I delete the configuration files and clear local files before resynchronizing, the issue is resolved temporarily. But next time I switch computers, it still has a high chance of crashing and exiting.

Steps to reproduce

1. At least 2 computers installed with the Windows client
2. First, open one computer to modify some files
3. Then, opening another computer may cause the client to crash

I also encountered the same issue.

If client crashes on files with non-english characters in filenames or path, it could be the same problem as in #7310

Me too, the Windows client can't start, and the files can't finish syncing. The server I'm using has MySQL as the database, and I can't find any logs about this issue.

Same here with windows 10, on many computers.
Nextcloud desktop 3.13.4 and 3.14.3, same bug, client crashes without any notification, so some people don't notice it's not running anymore, wich makes cooperation complicated...
Server 29.0.8.

It's really unbearable; I can't live without this software every day.
I recommend temporarily using the portable version of Nextcloud until this issue is resolved, and then switch back.
Portable version URL: https://github.com/portapps/nextcloud-portable/releases
It is recommended to use NextCloud-portable-win64-3.12.4-21.7z

An old user is extremely dissatisfied with the latest version of the client!

First of all, pay tribute to all developers!

The current stable version is 3.13.4.
Versions after 3.14. x, including the latest 3.15.0, either do not display localized languages, exit abnormally, or the program does not respond.
I don't know what has been modified in the latest version?
Is there such a big change?
And it's been 3 months and it hasn't been resolved yet. Imagine what would happen if it were used in a company with 100 users?

And by default, it still updates automatically without setting the language!
For administrators, it's really painful!

Finally, I would like to pay tribute to all the developers once again!

Hope to draw attention!
