I'm really not seeking any help resolving this issue, because, frankly, this has got to be the most absurd thing I've ever had to deal with. After probably 10 accumulative hours scouring the internet for solutions, tampering with bios settings, services settings, discord settings, rebooting my PC probably 150 times in 2 days, etc. Nothing has touched the issue. The last resort suggested is to completely reset my PC, which is confirmed to solve the problem for at least a few matches, but many report the error returns literally hours later.
I have no idea what on earth possessed Riot to implement this feature, requiring TPM 2.0 to be enabled to play their game (I literally cannot even upgrade to Windows 11 if I wanted to), but as of right now, the game is a brick on my PC because of this. I wish I'd seen a single announcement from Riot that this issue was even on their radar, but nothing. From what I've seen, it's caused a pretty significant portion of people to literally uninstall and move on.
