I've had this same issue due to the Get Object, Admob object, and String object.
Sometimes the blank canvas on as the first screen doesn't matter if a plugin is present in the file elsewhere. I had to systematically delete everything until it would build and run. Then I would go back a step until I found the half that made it run. Eventually, I got down to a single object. This has happened randomly probably 5 times over the last 10 years.
The object was up-to-date and looked and functioned fine. I simply deleted the object that was causing the issue, popped in a new one, and everything was fine again. Hope this helps.
