Another thought I had is that since you are on Windows maybe there is an 
AV program seeing the autovacuum as virus-like and killing it. Though I 
would expect there to be more errors in that case. Anyway it might be 
worth investigating should an upgrade not fix it.

It would be a good idea to upgrade to 15.7 in any case to get all the 
other bug/security fixes.
