Game has crashed and will not start even when downloading again.

The only thing I have left to do is finish the adventure game within the game. I'm at the part where you have to press the blue button and then cop the sequence three times. After many tries, I got the first one but now am stuck on the second. This is the only thing holding me back from finishing the game. Any tips?...

On 28 Jun 2021 I purchased part 1 on steam to try it out with the expectation that I could buy parts 2+3 if i enjoyed the game. I completed the game a week later, and have now found that all 3 parts have been removed from the steam store by the publisher. This is very annoying....
