[Squirrel-sql-users] Issue launching squirrel client

[Greg B. <gjb...@ho...>]

I have been using squirrel for many years. Normally, I can figure out any issues on my own but it seems I have a corrupt file somewhere and the stack trace is not helping. I am getting the below error when I attempt to launch the application. I have downloaded a fresh copy the latest stable build 4.5.1 and installed it in different locations (both the zip and the installer). I have tried Amazon Corretto [C:\Program Files\Amazon Corretto\jdk11.0.19_7\bin] and Eclipse Adoptium [C:\Program Files\Eclipse Adoptium\jdk-11.0.19.7-hotspot\bin] but EVERY instance has the same error. The splash screen starts gets about ¾ through then gives me this error. If I had any idea what file it is trying to read and failing at I would fix it. Please help.
