Seemed okay.
The only minor log warning was about the ban list file, which changed to JSON format in v22.

banlist.dat ignored because it can only be read by Bitcoin Core version 22.x. Remove "...\banlist.dat" to silence this warning.

By the way, one unrelated oddity are a few stray random-looking but fixed characters at the end of some log lines, in the "init message" phase.
