Issue should probably also be reopened as it is not solved yet.
I've tried tu use UNC path to .minecraft directory but it still doesn't work.
https://bugs.mojang.com/browse/MCL-10279 is in my opinion not a duplicate - it's about file system links, not UNC paths.
Hi, Linus,
and thanks for response. As far as I can tell, launcher version is 2.1.1462 but I don't know how to make sure it's the latest version. I couldn't find any "check for updates" or something similar.
I also don't know what "sensible repro case" should be. I can only tell, that if I enter UNC path to "Game directory" field in "Launch options"/"Latest release" it simply vanishes and the field becomes blank. The program then assumes default game directory.
