Had this same problem today. Whatever you do, DONT CLICK REPAIR in the windows apps settings. Any time you do this it will placehold another 50+GB folder in the mutable backup. The first time I clicked repair it seemed to neverend so I thought it wasn't working. I tried it a second time like an idiot and low and behold treesize found 150+GB of garbage sitting on my SD in the mutable backup.

I'm currently reinstalling for the 4th time. I really like this game but due to these reasons I have refused to spend any money on it till this issue is resolved incase I get tired of fixing it and quit.

I don't understand why you guys can't just move to steam sooner and accept that the microsoft store was a total mistake.

My only worry is that if the game moves to steam, this microsoft store account won't be loginable through steam for "reasons".

Is anyone else still getting glory badges from this? I think I got 16 today from VR training urgent quest but there is nowhere to use them that I am aware of now. Guess they are needing to be discarded? Be cool if it was dropping the Rising weapon badge 2's instead.

Was this ever fixed? I have a mutable backup folder that is 59gb. I have uninstalled the game once and had to reinstall. I noticed my SSD space becoming quite low and looked into it. I have a windowsapps and a modifiablewindowsapps folder. The windowsapps folder has a mutablebackup folder with 58gb of data. The modifiablewindowsapps folder has pso2_bin with another 58gb of data. I clearly don't need one of these and I'm guessing its the mutablebackup folder. I have been trying to get the permissions changed but have been unsuccessful. I was able to change myself to the owner but i am unable to change permisions to allow myself to delete it though, all the boxes are grayed out.

This is the most irritable thing I have ever encountered from a simple damn game installation. I wonder how many people out there are even aware of the complete fuckery of this system and have this data locked onto their SSD unable to delete. I bet alot of people don't even realize it.

What am I doing wrong and is there another way to remove it?

-Edit: I was able to get permissions changed. Not sure how or what caused it but the full control box became checkable.
