Unexpected behaviour since Windows 1903 Update

Good day PG team,

We have noticed some of our clients' backups not being created since the 1903 Windows update.

We are struggling to find the cause of the problem and decided to rely on you for guidance.

We have a scheduled task running a backup.exe which is essentially a java ProcessBuilder gathering all the databases and dumping it with pg_dump.

After the update no backups seem to be created and the logs just seem to stop at the the psql --version command.

Log from broken machine after Windows Update:
