Welcome to the Magix Sound Forge users community @John-Walsh5524.
First, try "Reset all preferences and clear cached data"... Assuming you cannot access the "File" menu command, use the alternate method: Hold down the 'Ctrl+Shift' keys, whilst launching Sound Forge.
If that fails to resolve the issue, completely uninstall Sound Forge using a third-party uninstaller and reinstall. I recommend using 'Revo Uninstall' choosing the 'Advanced' scan mode. Revo will uninstall and remove the left-over registry entries and other pertinent data the OS uninstall leaves behind, which can cause an issue to reoccur.. Revo Uninstall has a pro and freeware versions. The free version is adequate in most cases.
@John-Walsh5524 Ok, thanks. That's interesting. Have you installed new VSTs between the last time Sound Forge has worked fine and today? Sound Forge scans VST paths on each start.
Try the reset tip from the post above. This could help.
