Updating an External SSD

Bought an external SSD because it’s faster. My 2017 IMac is on Ventura 13.2.1, so I put the MacOS on the SSD.


When the recent update came out, my IMac updated fine, but the SSD snagged and won’t finish. Anything I can do to 1.) free up the SSD and 2.) complete the update?

All it says in about 6 languages is that my computer restarted because it has a problem.

iMac 21.5″, macOS 10.12
