When I use mklink to import the .minecraft directory elsewhere, the old version of MCL can run very normally. But when I use the new MCL app, the launcher can't open (screenshot1)

mklink /D .\.minecraft E:\Game\Other\Minecraft\Data

When I try to restore .minecraft and then mklink the "assets", "libraries" and "versions" directories, I try to start the java version of minecraft, but the file cannot be downloaded (screenshot2), or the launcher crashes directly

mklink /D .\assets E:\Game\Other\Minecraft\Data\assets
mklink  /D .\libraries E:\Game\Other\Minecraft\Data\libraries
mklink /D .\versions E:\Game\Other\Minecraft\Data\versions

There is no problem with the old MinecraftLauncher.exe

It is suspected that the related API has a special judgment on the directory created by mklink

It seems to have been fixed in the latest version (2.2.7450)
