backend error after upgrading to 3.6.0

Hello! We have stumbled upon a strange issue after upgrading from PostGIS 3.3.0 
to 3.6.0.
A simple query like  select * from foo.bar where ST_IsValid(geometry)  executed 
in DBeaver returns the following error:
SQL Error [08006]: An I/O error occurred while sending to the backend  if the 
size of this table is like 6 Mb or more. While executing DBeaver shows 
something like connection attempts and finally invalidates/reconnects with this 
error message.
