I recently started working with MetaSound so it may or may not have something to do with this. I also discovered that renaming the config folder actually would fix it…and after putting it back it would start working again but as I continued working with accessing MetaSound Variables from a blueprint it would start doing it again. The Bug: After Working with MetaSound Variable Access from a Blueprint I would go back to the viewport…but it was frozen…only the viewport, I couldn’t rotate, but when I tried it would look like 1 frame would render…when pressing play, it would be solid black…not rendering anything… What I am NOT Doing: Setting it to not Render In RealTime…It is In Fact Rendering in Real Time…look closely at the picture. What I have Tried: Restarting The Project (Doesn’t Help) Restarting My Computer (Doesn’t Help) Reinstalling My GPU Drivers (Doesn’t Help) Renaming Config Folder (Fixes it Temporarily) Delete Saved Folder (Also Seems to Fix it…not sure how long this will last, I just now tried this) My Specs: Intel i9 12900k Processor 64 gbs 3200 Corsair DDR4 Nvidia 3080 Ti 12gb Samsung 2Tb Gen4 SSD ScreenShot of Frozen Viewport: ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/a/a/daaf30ad0cb0572ec6fcb09078f0a5240e866ab9.jpeg) ScreenShot in Play Mode: ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/1/4/514c7e7a2f54d1b4c8218f08a59b249a5d34ed7b.png) ---

I am wondering if this bug could be related to the AutoSave bug? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/5/2/152d4c89c0bc54f5cb58724a11c1905c33e3d13a.png) ---

Nm Tried deleting this and it didn’t help…process of elimination…I’ll delete piece by piece until I narrow it down to a specific file and return with the results ---

So, Deleting the Saved/Config folder fixed it but now I can’t recreate it so I’m not sure what file exactly caused it because putting the folder back after (having started it and removing it) didn’t break it again oddly enough. ---

Deleting this out of the EditorPerProjectUserSettings.ini from the Saved/Config/WindowsEditor fixed it…this is without a doubt a bug
