What are the questions I have to ask potential users when I validate my idea? (in a survey) questions To know the pain and it really needs a solution for it?
Do you need to do this via a survey? Personally, if I'm at the early stages of idea validation, I always find the best way is to have an in-depth discussion (either face to face or via video call).
If you haven't seen it before I highly recommend a book called The Mom Test which talks about how to have conversations with potential customers without biasing the answers:

Thanks, @georgiabaz, but my idea is about the content creators and influencers I don't know anyone, so I think it will be hard to make a video call with them!
Ask your friends if they know someone. Or ask here in the community if anyone is a content creator and willing to participate in a 15 minutes user interview. When you got one interview, ask them if they know anyone else you can talk to (content creators know other content creators).
Especially in the early stage it's important to have an open conversation to really listen to the problem and the context of it.
There is a great video about the questions (oriented on the mom-test) from Y-Combinator: https://www.youtube.com/watch?v=MT4Ig2uqjTc
Try not to do surveys. At the early stage you want to talk to as many people as you can. Survey questions can be perceived very differently.
