Battle.net - We couldn't access a folder. This is usually because you're not logged in as administrator

[Kenst1092]

I successfully installed Battle.net on Ubuntu 22.10 using Lutris and WINE, and pointed Battle.net to my Overwatch 2 install, located on a separate drive whose filesystem is btrfs. Battle.net needs to update this game, however when I click "Update", an error is spat out, saying "We couldn't access a folder. This is usually because you're not logged in as an administrator".

I have rwx set on all files in the drive that Overwatch 2 is located in. Is there any remedy to this? If not, I have Ubuntu dualbooted alongsides Windows 10, where I also have a Battle.net install for playing Warzone 2 (because kernel-level anticheat does not work on Linux) - would I instead be able to remedy this problem by updating Overwatch 2 in Windows?
