Visuals freeze after a few seconds but the game itself does not

I will press the play button to test my mod, load into a world, play around for 20-30 seconds, and then the game viewport will freeze.
The game will freeze visually (as in the window will become a static image), but if I press WASD, I still hear the footstep sounds, left clicking still makes block breaking sounds, right clicking still makes using item sounds assuming I had something usable on hand, so for all intents and purposes the game is still running, but the window visually appears to be a static image.
This first happened with a mod that had an "on player tick" procedure, but since then I've tried with completely new empty workspaces and the same issue occurs.

Computer specs:
-Intel i5 11400
-NVIDIA GeForce RTX 3050ti
-16 GB RAM (4 of which are allocated to the game as per the default settings)
