Bitcoind logs "2022-01-17T19:07:16.160208Z ERROR IN SIDECAR: No such file or directory (os error 2)"

This was after migrating from 0.2x (running off an SSD). The problem started after IBD was completed. Bitcoind still ran fine afaict.

Restart stopped the issue but it may begin again after some time - I will monitor.

Closing for now - probably fixed from v23.0.0 update
