Since upgrading to Ventura, two identical external ExFat drives cannot be simultaneously mounted.

I have two identical 5TB external ExFat drives, with different naming and content. I used to have them both connected and everything worked fine obviously. Since Ventura, only one of them can be mounted at a time. Both of them show up in Disk Utility but the one missing has the icon you see below. Furthermore, I am having issues with empying files from ExFat drives. A message that the file is in use keeps coming up.

Hello ioannis228,

We see that you're having an issue with external storage devices and we have some steps that can help with isolating this issue. First, start your Mac in safe mode and then test to see if you're still seeing the same thing. the steps for safe mode are outlined in the resource below.
