Cannot get into world, kicks me out after two seconds without hit coming error code

It started with a problem going through the nether portal in my base. If I used it my world would kick off saying “an unexpected error had occurred” if I used a portal farther away it didn’t seem to happen. I was bringing frogs to the nether for a frog light farm and this crash happened several times. With last time not letting me back in with errors again. I went through forums and mojangs suggestions. Nothing has worked. This is not the first world I’ve lost to errors. I’ve spent so much time, I don’t want to start over. I’m hoping this can be fixed and I won’t lose this world. I don’t plan on continuing to play this game if I lose another world. I have attached the error message it says to summit to you. Thank you!
