I have been unable to get 1.17.1-forge-37.0.108 working on my machine. I just recently updated the Microsoft Launcher, and saw your post about "known issues", but I can't quite follow what it is you're telling me to do. I'm pretty new to Forge, so it's not quite obvious to new users like myself. Which files are "the appropriate JSON files"? Where are you supposed to add _microsoft_store? To the end of the filename? To the last line of the .json file itself? Could you show an example?
