It’s was taped originally and cracked. Fixed it with tape again and it cracked again. Taped again, tree falls on house, cracked again, just kinda foo fooed it last time. I’m thinking something flexible.
I think there is a lot of movement there. I hear creaking and cracking in that room. Especially in the morning when the sun hits it.
I think you'll hear that in any house. I know mine does that when it's cold out. You turn the furnace on and you'll hear it. Expansion and Contraction but it doesn't crack the drywall. You may have to cut that section of drywall out and see what's going on or you'll be fighting problem forever. Good luck with it.
