When I press "Yes" in dialog to remove configuration the configuration is not being deleted and I have an error in terminal.

But the previous launch of PlayOnLinux I could remove a configuration without any problems.

I use PlayOnLinux 4.3.4 on Linux Mint 20.3 Xfce.

The error occurs when environment variable LANG=C is used.
