Game crashes everytime I try to use portal to escape the nether ever since update1.19

After last update I am trapped in the nether after entering. Every time I try to use portal and leave the nether the game crashes. IT kept crashing at my portals in more used areas even after you claimed it was fixed. I could no longer use my nether portal for my my base but I used to be able to use the next closest portal and get to my base from there. Ever since last update however I can not use any portal without game crashing. Not only has it crashed the game but the bug reporting page froze up and I had to risk memory damage to my psp4 due to having to unplug it in order to unfreeze screen.
