Useful Info

OS: Windows 11
Ver: 4.4.1.1441

There are lots of things going on when SGPro starts so we’d really need to take a look at logs showing the failed startup. We have some information here on how to get to logs when SGPro won’t open. In addition to that, we have kind of checklist of things you can try. If none of those things work, we’re glad to inspect the logs…
