Is this repeatable? If so you've found a bug, I think.

Yeah, what this really indicates is an incomplete read (file shorter than
expected). Since 11.8, we've improved the error reporting for that, but
that wouldn't in itself fix whatever the underlying problem is.

That could be the proximate cause, although then there would be a bug
that the original write failure wasn't detected. But it seems about
as likely that there's just some inconsistency between what the temp
file writing code wrote and what the reading code expects to read.
Is this a parallelized hash join by any chance? That's new in v11
if memory serves, so it'd be interesting to see if disabling
enable_parallel_hash changes anything.
Anyway, I'd counsel updating to current (11.11), and then if you can
still reproduce the problem, try to reduce it to a self-contained
test case.
