Game launch crashes when using windows symbolic link for minecraftWorlds
_____________
Steps to Reproduce:
- Backup your minecraftWorlds before!
- Delete minecraftWorlds
rmdir /q /s "%UserProfile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds"
- Delete TEST folder if exists
rmdir /q /s "%UserProfile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\TEST\minecraftWorlds"
- Create TEST folder
mkdir "%UserProfile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\TEST\minecraftWorlds"
- Create symlink
mklink /J "%UserProfile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds" "%UserProfile%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\TEST\minecraftWorlds"
- Start Minecraft App
- Create a new world
Observed Results:
Error,
"There was a problem loading this world"
Expected Results:
No error, world should be created and placed in TEST folder
There seems to have been a change in behaviour since version 1.17.34, before with symlink Minecraft app crashed on start, now it starts and crashes on world create.

There seems to have been a change in behaviour since version 1.17.34, before with symlink Minecraft app crashed on start, now it starts and crashes on world create.
I did some more testing and discovered that symlink only works if the target folder is placed under the LocalState folder or sub-folders.
Is this an expected behaviour?
Here are the cmd tests I made:
Still happening on new release 1.16.220 and no activity on this bug...bump
Still happening on new release 1.16.221 and no activity on this bug...bump
Still happening on new release 1.17.0 and no activity on this bug...bump
Still happening on new release 1.17.10 and no activity on this bug...bump
Confirmed the same behaviour. I do this all the time so I can have save games synced in dropbox between my desktop and laptop; I've done this with at least 40 other games, I've never hit an issue like this before. This is definitely a bug of some kind. I can't even imagine what would cause it, though, since junctions show up to programs as just another directory.
Side comment: "mklink /j" makes a junction, "mklink /d" makes a directory soft link. In either case, the MCPE Windows App crashes at between 42% and 46%
Since I assume other people reading this are trying to do multi-computer sync of world data: I was not able to work around this with Dropbox or OneDrive. It might be possible to do with Google Drive, I didn't try. However, what I did end up doing is using Allway Sync to sync between my MCPE data folder and a folder in my Dropbox folder, that does seem to be working.
Thank you for your report!
