Failover Testing Failures: invalid resource manager ID in primary checkpoint record

My hope is I could just start the old primary / new replica if it was cleanly shutdown prior to promoting the replica. However when I try to start up that new replica, I'm met with:

It doesn't appear any WAL files are missing as it finds all the files that it asks for. Am I missing a piece here?

My hope is to avoid having to do a restore to rebuild the new replica.

Aside for those that may be asking: most of these databases do not have data checksums enabled so pg_rewind isn't in the picture. Although I'm reading now that we could enable the wal_log_hints parameter as an alternative. I'm leery of the overhead but if it's the same overhead that would be done with data checksums then I guess there would be nothing lost when we eventually enable them.
