Nextcloud client windows10 crash on setting proxy at setup

at work we have access to the internet via a proxy server.
It happens that if I change the password to access the proxy, nextcloud client (windows 10) no longer accesses my server and it says “the proxy server requires authentication”…
the problem is that even if I go to the personal settings of the user connection, and change the password, the client does not connect to the server… if I then go to the global settings, as soon as I set the parameters of the proxy server, the program crashes.
It had already happened to me some time ago and I had to remove the entire program from the PC.
Some time ago, after completing the installation, I was asked for the connection parameters, but now the installation ends without any possibility of choice.
I have removed the nextcloud client program several times, also deleting the local user files, the program folder and all the values ​​of the Windows configuration registry, but when I do the new installation it no longer asks me for the connection parameters, and it continues to crash when I try to configure the connection in the “network” tab.
How can I proceed? Thanks

I found out that it is a bug, but I don’t know if it is fixed because the problem is still there today 30 April 2025.

thank you for your support.
