Yes indeed SWT = Eclipse's Standard Widget Toolkit. As you can see in my post there's a link to a bug regarding this issue.
However, as pointed out, this error is not limited to that framework. It's crops up online reported by users of various applications.
It's only started since Big Sur & Monterrey - it doesn't occur on Catalina or earlier.
It can be triggered using a colour panel in System Preferences > General and setting the Highlight colour as described above, which of course is all Apple's own code.
If it helps I can aim to get a screen recording demonstrating that... (A crash report from that is actually attached above also)

Confirmed, working for us again also now..1am here, time to rest and, thankfully, relax!
Also started having problems with notarization today.. Have you checked the logfile for details?Our logfile output indicates that what were warnings are now again errors (in our case "The binary uses an SDK older than the 10.9 SDK.")Have Apple reset the loosened notarization prerequistes back early? According to the below news article this is supposed to happen on Feb 3rd!https://developer.apple.com/news/?id=12232019a
