ue crashes after updated to 5.1.1 and switch to NVIDIA 4090

Hello,

I can no longer work on my projects that use niagara.

I replaced my graphics card from an RTX A5000 to a 4090, installed ue 5.1.1 (my projects was saved with version 5.1) and now the software crashes every time I try to open a map.

I ask for help, I have spent 2 or 3 years on this project and I really need to finish it.

Thank you so much.

Giancarlo
