The external SSD's 'Security Mode' is also turned off with no password required. However, both 'FileVault' and 'Firewall' are turned on under System Preferences → Security & Privacy not exactly sure if either would play a significant role in causing the issue. In addition, 'Firmware password protection' is turned off. I did make sure to boot internal HD using Recovery Mode, went to Startup Security Utility and under 'Allowed Boot Media' enabled Allow booting from external or removable media, along with 'Secure Boot' being set to Medium Security. Most interestingly, when I view it under System Preferences → Startup Disk, it's shown as indeed already running on macOS 12.2. I'm even able to eject it and plug back in with it immediately showing up as connected device. It's showing up as a readable/writable device, its info shown in Disk Utility confirms it as bootable, I've been able to run 'First Aid' on it a couple of times (no errors ever found), and it still has plenty of space left (only 460GB used). MacBook still boots perfectly fine using internal HD as startup disk and, very surprisingly, I'm then still able to access and fully view the SSD this way. Numerous further attempts have been made to boot using external SSD, with the exact same result occurring each time. A few minutes went by with fans running and progress bar stuck, then suddenly fans surged to loud revving sound and MacBook immediately shut down then restarted itself.

Progress bars advanced and remaining time was given throughout process, but once update seemingly finished and MacBook restarted - for what I assumed to be the last time before finally booting up with new OS - the progress bar under the Apple logo (with no remaining time indicated underneath) made it about halfway through before fans kicked on. Update appeared to be installed correctly, for the most part, although took a bit longer than it probably should have.

Wanted to also update software on external SSD to Monterey, and went through normal process to do so. The internal HD is already updated with Monterey and working just fine. I've been using Samsung T5 SSD (connected via original USB-C cable directly into Thunderbolt 3 port) as my preferred startup disk for a few months now, with everything previously on Macintosh HD cloned to it.
