Could you provide a backtrace?  Looking at the recent commit history,
we had one fix which could be relevant to you after 12.1 was released:
https://www.postgresql.org/message-id//[email protected]

And here is the commit:
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=a2aa224e

The problem may be different though, so a backtrace would be good to
check anyway.
