I have been very happy with my Ubuntu 20.04.4LTS system until a few days ago when I installed the 5.13.0-40 update. When installing this update the installation process seemed to freeze removing an earlier update (cant recall which one). I waited an hour to see if it would complete but no change so forced a shutdown and reboot. System rebooted running the -40 update but was variously unstable. It might hang on the Ubuntu boot screen with the spinning wheel thing, or may go further but just freeze a short time later. Booting into the -39 kernel from the grub menus works fine, system stable as expected. Booting the -40 the same way gives same problems.
Basic system
Dual boot, Ubuntu and W10,
ASUS ROG STRIX Z690-A GAMING WIFI D4 LGA 1700 ATX Motherboard,
Intel Core i7-12700K 12 Core,
Corsair Vengeance RGB PRO 32GB (2x 16GB) DDR4 3600MHz CL18 Memory,
2x Seagate FireCuda 530 1TB PCI-Express Gen4x4 NVMe M.2 2280-D2 SSD (one for Ubuntu, one for W10),
ASUS GeForce RTX 3080 TUF Gaming OC V2 10GB Video Card - LHR Version,
LG UltraGear 34in UWQHD IPS 165Hz G-Sync Compatible FreeSync Curved Gaming Monitor (34GN850-B),
Corsair Keyboard.
Any help debugging would be very much appreciated. Will gladly run any commands and supply output to assist in diagnosis.

Thank you Joepie Es for your assistance.
I altered grub to boot the -39 system. Then followed your instructions (with a little edit to add the "-generic" to packages I was removing. This left me with a single function version of the system, -39 which boots and runs without problems.
Where to now? Do I just cut my losses and wait for the next update, or do I bother to try and get -40 correct? Is there a simple "kick off the failed update for a second try" command?
Peter
Below are the commands I executed:
$ sudo dpkg --list | grep linux-image
