What causes this behaviour? Going on throttle and engine revs but car doesn't move.

Ibishu BX-Series (vanilla), all the used parts are vanilla as well. Car setup at the bottom.
I am rather knowledgeable about cars and tuning, but I cant find the cause for this.

I tried to take/learn from the settings of the drag variant of the car, but this keeps happening and I don't know why.

I do sometimes get clutch temperature warnings, does it just break?

Really appreciate your guys help, I am lost what causes this.

I also summarized it in this post as well (not the car in the video here)
