Sub panel records causing error on new install of Suite 8.3.0

I just installed a new instance of Suite 8.3.0 through softaculous. Building out a quick app - two modules. One for services, one for sub-services. Services has a 1:M relationship to subservices. A few custom fields in it, but nothing outside of module builder. When trying to create a new record on sub services through the sub panel from services - it continually errors on the record. Can’t find anything that stands out in the logs, doesn’t save the record, just doesn’t seem to work. Have done full rebuilds of all options in the repair section. Running on php 8.0. Have tried a clean install twice with the same results. Don’t see anything else on here yet about it, so figured I’d see if anyone is having similar issues and has figured out what’s going on.
