I’ve created a brand new Blank Project that doesn’t use the Starter Content or any of the template packs.
Prior to adding this Blank Project to P4 I can open it just fun. But the moment I add it to P4 and then try to open it, from the Launcher’s Library, the editor will crash around 90% into loading and give the following error
Unknown exception - code 00000001 (first/second chance not available)
