I am having the same issue. on Win11 first when I installed V0.90 it was in English then after the restart of the computer the program changed to French. Even I chosen a new language it stays French. Before commenting on it I have pressed OK.
I uninstalled reinstall still French not possible to change language. Then I tried with with 0.100 version same issue. Any suggestion or idea? I can't speak French....
Found the issue. If I pinned the program to the TASK bar an I opened it, it opened only in French. If I started the program from the desktop shortcut it started in English. I struggled 3 days with it...
