Thanks, you pointing out the difference between romex and UF got me to go back out and specifically check the cable. It is in fact UF. I didn’t realize cable could be buried directly like this without some sort of protective conduit the whole way so didn’t think to check the level of cable it was.
I think I will do what you and a handful of others suggested, and disconnect the breaker then replace the pipe from the top. I think I will also get an AFCI breaker that was also mentioned just in case.
