Hi Cuthbert, Could you please try below steps to rectify your issue:
1. Take a backup of your 'pgadmin4.db' file which is present at the %APPDATA%\Roaming\pgadmin folder. 2. Delete 'pgadmin4.db' file. 3. Download pgAdmin4 v5.3 from https://www.postgresql.org/ftp/pgadmin/pgadmin4/v5.3/windows/ 4. Install and Launch 'pgAdmin4 v5'. Also, I would suggest you to use the PostgreSQL 10+ or 11+ version as the support for 9.6.22 would be lasting till Nov-2021 to get better support of pgAdmin4 application.
