Crash with error CE-38700-8 when entering netherportal

Good afternoon,

 

Afther the 1.18 update my minecraft world gives an error when I entering a Nether poral to leave the nether. When I enter the portal the game try to load the overworld and gives then the error CE-38700-8. I play this world since 2018, and it is 953,1mb...

I don't have a copy anymore because this copy was also giving errors.

 

Is there a solution? Thanks.
