Redhat 7.9 VM not working after latest update

Hello, I have a Redhat 7.9 VM on Windows 10 Hyper-V. It was fine, but after I applied the latest update, on boot the VM doesn't start. It shows a black screen with a some odd red symbol on the top, and it doesn't start. I attach the log file of the installation.

Any help would be appreciated.

Thanks, Marco
