Kirby's Return to Dreamland: game file won't start after playing 100%

[Kimbanton]

Today I beated the final boss, have collected all 120 energy spheres and played all the ability challenges in Kirby's Return to Dreamland!!! And then after I started the game I normally got to the Start Screen. I wanted to play in my game file with 100% a random level, but when I started the Main game, there didn't load anything!!! Just a BLACK SCREEN!!!! I couldn't enter or exit it!!! I restarted it and tried it again!! It happened every time!!! I don't wanna lose my progress!!!! Please, do you know how to fix thet crash?

I'm using Dolphin 5.0

Use latest dev build. 5.0 is old at this point.
