This error is really common and is caused by windows via UAC, SFC, Firewarll, AV etc.. for it spontaneously to appear means system config change happened or update occurred.
Common sources windows updates, anti-viruses changes, firewall changes.
If its not the above 4 figuring out what causing this is near impossible as something is trying to access a shared memory resource that does not have access rights to it or app that is accessing it is has a bug and corrupting PostgreSQL memory.
Given this is localhost connection, start looking at firewall or AV.

Hi!
Every time when user tries to log on from same virtual computer where
Postgreql resides, Postgres terminates with 0xC0000005 exception. Log is
below.
About 65 users are accessing this server over VPN. They can use server
normally.
Logging from localhost using pgadmin 4 with user postgres also works.
Only any attempt to log on from localhost with user dbadmin from psqlODBC
client causes this exception.
It has worked normally for many years but now suddenly stopped working for
localhost.
How to fix this ?
