One of my projects (only use GMS 2.2.5, so should be no problems) now throws an exception when selecting it as the source. I think I was on the older version of Resource Importer, but installed the latest one and it still occurs. The .yyp is valid (passes a JSON linter) and loads fine, so I'm not sure what the problem is. I imagine this might not be fixable given priority is probably supporting 2.3, but thought I'd report it, here's the log.
