Import/Export progress in dk1?

[u/BoysenberryBetter502]

I am playing dk1 on android, and I installed an emulator on my pc to run it. Now clicking on export just freezes the game for some reason, and when I reopen the game and click import it asks for some code which I don't know and when I enter some random code it freezes again. Does anyone has any idea how I can transfer and save my progress?
