I suggest to try
A: How much free ram does your AmikitOS have btw?
(CandyFactoryPro eats a lot of memory)
You might simply have forgot to set your winuae config to 64MB of ram or more.
B: Turn off JIT. CandyFactory will be unusably slow but at least you will know if it can start up or not.
C: Load the program NOT from Magellan desktop but instead boot amikit with either a plain workbench desktop or a Scalos desktop THEN load the program.
Does that work?
D: Edit the icon to have a huge stack. Maybe stack=2000000
If you can get it running then please feel free to make some gfx for my Amiga game with CandyFactory
