Who should I contact? New homeowner

I recently bought this 1955 home about 7 months ago. Full inspection done and no major red flags.

I noticed a crack in my kitchen ceiling last night and trying to figure out who to contact to take a look at it. Seems to be drywall. Not sure what the cause is… but I’m nervous as a first time buyer!

*note - scared to go into the attic above to check it out as we were told there is vermiculite insulation and there are no issues if we do not disturb it.
