photo library error 4302 on big sur

hello, i am having troubles with the new OS update on my mac, i have completely transferred my system photo library on my external drive to ensure enough space for the update, last time i checked it before updating, it was working. but when i already installed big sur, it says that it cannot be opened, error 4302. i have repaired the library, tried repairing it on the safe boot many times, but the drive i have connected isn't showing. can someone help me out on this? it's so frustrating

Hi


Every time I've seen this message in the last couple of weeks, associated with 11.5.1 or higher, it has been because the library is stored on an external volume with an incompatible format. Normally it is ExFAT, because that is the default for a new drive.


It looks to me that Apple have decided Photos will no longer work with libraries on ExFat drives, and possibly any other incompatible volume.


If this is the case here, you'll need to move your library to a compatible volume (Formatted APFS or MacOS extended (journaled) with the ability to set the ignore ownership flag. The volume must also be directly connected (USB or Thunderbolt), not networked (No Ethernet, no Wi-Fi)
