This is a problem with optifine, not vanilla.

I'm booting up with 1.20.1 vanilla and the problem still occurs

Are you using any resource packs? If so, please check if the issue persists after disabling them. Otherwise, while the text is displaying incorrectly, could you force a crash by holding F3 + C for 10 seconds? Then attach the crash report found in [minecraft/crash-reports/crash-<DATE>-client.txt|https://minecrafthopper.net/help/finding-minecraft-data-folder/]. Thanks.
