Hi, I've been using Minecraft through OneDrive for years (but I had to suspend OneDrive while playing, otherwise OneDrive would crash), and today I tried to go back to Minecraft, I encountered the same issue. I can confirm it's because of the Files On-Demand feature (but I don't know what exactly happens when the launcher tries to access to the files...), it does this with the version json too (my .minecraft was symlinked to OneDrive, just after the Windows update my symlink became broken, so I did another one and, even if it works in the windows explorer, Minecraft can't "access" to its files, while it can read and modify the launcher_profiles.json stored on OneDrive...) My Minecraft folder is already "always on my device", though. I think Microsoft severely modified the OneDrive folder properties (it's seen as a... file, not a directory, from Ubuntu), notice how Minecraft replaces C:\Users by C:/Users... and it still won't work even if I completely close the OneDrive client.

OneDrive should automatically download the online files the launcher tries to access (while they are downloading, the launcher may hang, but that's not a big deal), but I don't know why it wouldn't work when the files are downloaded.
