I need a really strong hook that can withstand the pressure. Preferably with 4 anchor points. I'm thinking of securing it with 4 anchors. There are commercial options available but for example, €230! Insanely expensive.
Can you drill a hole through the wall and place a regel at one end of the line? So the line goes through the wall with a regel as a lock, place the line close to the ground for more stability! I've never tried slackline but I climb a lot! Otherwise, you drive a 70*70 impregnated post into the ground and place 2 supports that are driven down at a 45-degree angle and attached to the vertical. The posting is done towards the anchor tree and laid back against the post, make sure you get a good height so you just slide the loop over!
You can always bolt an anchor on top of the rocks (so the direction of pull for the bolts is correct and can withstand your load with margin). Cost a few hundred, preferably two anchors and a chain.

Otherwise, you drive down a 70*70 impregnated post in the ground and set 2 braces that are driven down at a 45-degree angle and attached to the vertical. The piling happens against the anchor tree and laying backward against the post, make sure you get good height so you just pass over the loop!
Hmm, it's granite and the wall is probably more than 30 cm thick so it will be difficult. Setting a post would have worked but I would rather find a good and strong hook, the simplest and neatest solution in my case. Just need to find the right product
