Can't start. "Missing cached shader map.."

Hi everybody. Hopefully somebody can kindly chime in!

I’ve just installed 4.10.4 and I was working on a project created with 4.9.

The project started crashing a few times under 4.10 untill 15 minutes ago when I can’t seem to load the project anymore.

I’ve also tried moving the assets into another project and load the map from there but nothing.
I always come up with “The following process has crashed: nameofproject”.

I have to say before upgrading I deleted the content of the “deriveddatacache” folder to free some space. I start to think this was a bad move.

and this is a log of the crash:

Hey rodo3d,

Try deleting the entire ‘Derive Data Cache’ folder instead of just its contents. Then try renaming the folder for this particular project to see if that resolves your issue.

Let me know if you have further questions.

Cheers,

Thanks Andrew,
I was in a pretty urgent situation so it was quick enough for me to rebuild the scene.

Thanks anyway
my best
