Thanks for getting back about this.

A fix for this bug will appear in Postgres 14.1. In the meantime I
suggest that you avoid using parallel VACUUM. For example, any scripts
that run VACUUM could be temporarily changed to make sure that
parallelism won't be used. If the script says "vacuum my_table;", then
that could be changed to "vacuum (parallel 0) my_table;", for example.
Just until you can upgrade to the next point release.
