Default XC70 2.5t automatic - stuttering on acceleration.

Hey guys,
I have volvo xc70 2.5t 154kw automatic and for the last few years I've been postponing on finding a reason what is going on. But recently I've found a video showing the same issue, but there are no comments I still do not know the solution.
I found various different posts regarding ignition coils, spark plugs, transmission, electrical issues and ect. But fixing everything in a row is expensive. I think this is the best place to find out the exact issue, so I am gonna give it a try.

So basically, when the engine is cold the car is running fine-ish. The stuttering is less noticable and way more subtile. After the car warms up, the stuttering becomes more often and more aggressive. It feels like slipping clutch, but at the same time it feels like a missfire. I did run a scanner and it showed that the clutch is indeed slipping. But after watching tons of videos, I did not find any video of slipping clutch acting like mine is. That was until recently I found this video (Ill leave a link down below). It does not say what is the cause, but this is exactly how my car acts.

Could this really be the clutch slipping? Ir is it more possible that this is some kind of an electrical issue? Bad turbo? I hope that someone had something similar and can point me in the right direction to fixing it but honestly anything helps.

P.S Also regarding similar issue - could it be that the clutch slipping code came from the issue where when going for ex. uphill in low rpms and then flooring it it starts shaking and rumbling and pretty much stops accelerating? But then shouldnt the rpms go up when clutch slips? Because it feels like car hesitates, starts rumbling and choking
