Fork Fucked?

I have had this bike (Stumpjumper alloy) since 2020 with stock suspension. I had the fork rebuilt by Dirtlabs this spring (went through the shop). Had this and other issues after that and they warrantied their work and rebuilt it again last month. Now the same issue is recurring after only 2-3 rides since it was redone. It rode great before this happened. It's been a frustrating process after being told everything looked good during the rebuild (twice) to have this same issue occur again. I had trips planned starting this weekend and now I can't ride. Pretty bummed. I can't figure out why it keeps happening after being told nothing was broken on it….something has to be broken for this to happen right?

Part of me wants to buy a whole new bike since I've been thinking about it for a while. I'm tired of dumping $ into this one. Just wasn't planning to buy one this year, was thinking next year. Ibis Ripley or Ripmo?? $5k is the top of my budget…

Just ranting here. It's impossible to diagnose issues on the internet so I'm not really asking if it's repairable. Im assuming it needs to be replaced/upgraded to get it rideable again. But I've lost faith in RockShox bc of it and am so frustrated that I may throw down for a totally new bike since the fork isn't the only thing I'd want to upgrade on my current one.
