Retroarch crash on np2kai hdi load

I don’t know if this is the correct place to ask about this, but when loading some hdi files on Retroarch np2kai i get the following screen and retroarch crashes, game runs fine when using the hdm files though, and i did try the hdi file on standalone np21nt to see if it was just the file but it ran no problem there, can anyone help me? xD

already figured it out, just reversed to previous core version.
