Unable to run dev on any projects.

Somehow my environment is no longer able to run locally any worker. I even created a fresh "Hello World" worker and they all give the same error (see below). I noticed that I had lots of workerd processes running and killed them all (CPU was buring). Same issue after. Restarted, still same error below. Any suggestions?
