NVIDIA driver is not loaded. Ubuntu 21.04

I have an issue using: Ubuntu 21.04 5.12.11-051211-generic and GeForce GTX 1650 Ti Mobile. I can’t load the drivers and this is what I get:
nvidia-bug-report.log.gz (127.7 KB)

nvidia-smi: NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:27690): GLib-GObject-CRITICAL **: 11:43:16.219: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed

** Message: 11:43:16.227: PRIME: is it supported? no

dkms status:
nvidia, 460.91.03: added

no blacklist_nvidia.conf file exists

When I try dkms install nvidia/460.91.03 I get:
Error! Your kernel headers for kernel 5.12.11-051211-generic cannot be found.
Please install the linux-headers-5.12.11-051211-generic package,
or use the --kernelsourcedir option to tell DKMS where it’s located

Please find the nvidia-bug-report.log.gz file attached.

Any help will be very much appreciated! Thanks!
