Hey Ruby, I've had the same problem but now I've figured it out. Basically, I had the same situation as yours when my Sim was AT work/an event. When he was totally free and not doing anything, I clicked on the yellow arrow and it allowed me to enter the cooking hobby. Not sure if it'll work for you too but here you go :)
I'm having the same problem! I can't figure out what to do!
Weird bug...when my sim is taking a 'risky' action during cooking hobby that involves stove, she literally flips a second full size stove with a spatuala and when taking a 'risky' action involving the fridge, she again literally pulls a second full size fridge out of the existing fridge. I guess it is a 'risky' move...
