Movie Render Queue repeated shader compile /w Error code

Hello there, I’ve been running into an issue when rendering out a sequence in my project. It will repeatedly briefly compile every anti aliasing sample / frame, and is throwing up this error in the logs which I believe is the cause of it. I’m not getting this compile stutter on another project so maybe it’s something I’ve done? I recently made a quite heavy material, which from that point seems to have started it. Although even on new empty levels the compile error still persists.

Any help would be greatly appreciated!

That issue still persists

Update: To anyone who’s still struggling with this issue, try disabling the Metahuman plugin. This issue is known to EPIC and will be investigated.
