Just wanted to chime in.  Having the same trouble (Server 2012r2 - which I confirmed is supposed to be supported).  Only difference is mine isn't Enterprise (although I also have it installed and could likely confirm the same to be true).  I updated 2023 Pro and Ent over the weekend and now having all kinds of crashing issues (emailing invoices, etc).  Also having the "Something's not right.  We're unable to complete your request at the moment, try again later" screens upon intial login to a company file.

This is a reproducible issue.  Intuit, please fix and release another patch to address.

Regards
