a similar question was asked a few days before on the discord:

the answer to this:
Yes because your USB and SSD have same name on PARTITION “BATOCERA” rename your SSD partition in “MYBATOCERA” for example and now you can boot.
but if i understand you correctly, you only have issues when booting from the ssd (hangs/freezes)? then there must be something wrong with your SSD, SATA-Port or SATA-cable i guess.
try with another SATA-Cable, then another SATA-Port and then put this SSD into another PC to check if you have the same problems there (and/or use another SSD in your current PC)
