Upgrade from Linux Ubuntu 20.04 to 20.10 - nvidia-settings ERROR: NVIDIA driver is not loaded Unable to load info from any available system

I have simply upgraded from Ubuntu 20.04 to Ubuntu 20.10 (Dell 7530 i9) however now my external monitors do not work with recommended (or any) nvidia-driver-460 (The X.org X server Nouveau works on dual monitors but is slow/ buggy)

nvidia-bug-report.log.gz (170.5 KB)

nvidia-settings:
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

Is the linux-modules-extra package required for this to work?
dpkg -l | grep linux-modules-extra-$(uname -r) does not show anything

cat /proc/version:
Linux version 5.11.0-22-lowlatency

sudo apt-get install linux-modules-extra-5.11.0-22-lowlatency:
Package linux-modules-extra-5.11.0-22-lowlatency is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source ??

Any help much appreciated - I can’t be the only person that a 20.04 - 20.10 upgrade breaks their nvidia graphics drivers!
