Game directory not saved in the new Windows Launcher

Setting a game directory in the launcher 2.0.806 (lanucher options, selecting a profile, turning the game dir switch to green, copy/pasting a dir and pressing save) WON'T save the game directory. (The edit box is empty when returning) -> the game can't find the game directory and won't start.
Since the launcher can't follow junctions (linked dirs, unlike the old one) this is a problem. (Can't play with a tiny ssd drive and a huge MC dir)

I'm aware of the MCL-5047 issue that might be a duplicate, but the report a bug link takes me here in the launcher, so I'm guessing since this is already forced on us (release) you take bug reports here.

Thank you for your kind help.
