Cant open my world anymore

So i went on the beta and got a full set of netherite armor, after getting it i wanted enchantments on it so i went to my guardian xp farm, ( i use silentwisperer nether version ), usually i would wait 5 mins and then go through the nether portal, it would be laggy but i managed, but this was my first time using it in the beta, when i went through, my game crashed.

I thought it was a bug so i loaded up MC again and went back on my world, i was in the over-world for some reason, i decided my best option would be to go build another portal far away so hopefully my game wouldnt crash, i turned the difficulty to peaceful so all the guardians would despawn, then i built the portal and went through, my game crashed multiple times but i kept trying, then one time i wasnt able to load up the world, everytime i started to load up the world, my game would crash.

Hopefully there is a fix for this since i spent a lot of time on the world.
