I already tried removing the saved and intermediate folders but was told in the Unreal Engine discord to restore the saved folder I deleted and go into each folder under autosaved and remove the last part of the file names “_Auto5” or whatever the highest number was for each asset. Still this did not solve my problem.

Hey there @Matthew_Rumble! Welcome back to the community! Seems like there’s a material asset causing this error. Did you recently introduce some new or imported materials using the SingleLayerWater type?

Hi thanks I figured it out, it was due to a corrupt water material causing it to crash. I removed it and now it works!
