apt-cache madison pgadmin-4
sudo apt install pgadmin-4=<VERSION_BEFORE_9.13>

Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
