UE 5.1 Project crashes on Render or Preview for specific project

Hi,

I’m new to Unreal Engine.

Whilst I can load and preview the sample demos (First hour of UE, and City Sample) without crashing, I have spent a few weeks building a level which crashes withi na second of previewing, or rendering a few seconds of sequence.

The issue is only on this one project that I’m aware of, but I’ve spent so long building this, I don’t want to restart again.

Any help is greatly appreciated.

Many Thanks,

Update: I found an item in the project called ImgMedia… deleted this, and the preview now works without crashing.
