Hey,

I was able to open my windows fine until recently, some of my vision windows are getting this error. Does anyone know how to solve this, or why its happening? This is only happening to some of my windows, not all the windows for the project ☹

I can still see the preview of the windows when my mouse is over them though.

I typically see "unknown source" errors when something is missing, and an EOF error in this context indicates that the input stream is reaching the "End of File" before it should. Did anything recently get renamed, deleted, or moved?

Any Updates on this? I am having a similar issue and dont know what changed from the last time I was in this project. From my knowledge, nothing was moved or deleted or anything like that, but we do have multiple people with access to this project.

My error message is below:
