Start Electron get error about GTK version

[PatrickT80]

Describe the bug

When start the app, electron complaint about GTK version mismatch with this error:
Gtk-ERROR **: 19:37:57.074: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

On electron repository, the suggested solution is to use the:
app.commandLine.appendSwitch('gtk-version', '3');
as suggested here: electron/electron#46538 (comment)

But even if i wrote this in main.ts, electron complain about GTK version mismatch

3.1.0

I've tried to run electron without this lib and it run correctly without error; seems the command line not receive the arguments
