I am about to interview / ask questions from a single end-user, who has been using the application in prod for 3 months daily.

I am wondering is there some existing question set to begin this with? I would like to start with some existing question set and add some of my custom questions.

Topics that I'm interested in are as follows:

  • The usability problems of the current implementation
  • Possible alternative solutions (more radical approach to the actual problem)

So, I'm trying to confirm if the current UI design is valid --- or does it need a major remake. If so, what kind of?

Any help is appreciated.

One person's feedback will not be determinative, because this user can be an outlier. Depending on the complexity of the application you might need at least 5 people to uncover most problems. That said starting with recalling the last experience might be a good starting point. Something like, tell us about the last time you used this application/performed this task. How was your experience like?
