2016 taught me to never, ever predict with confidence what will happen in the Presidential election again.
Personally, I think Trump has far more to be concerned about than a potential 2024 run. Prosecutors in New York are zeroing in on him like a killer whale zeroing in on its prey and he could very well be the first President in history to face time in prison. Add in the fact that he is personally on the hook for hundreds of millions of dollars in loans due in part or in full in the coming months and you have a pretty exposed and vulnerable "frontrunner."
I don't think that means Trumpism will go away. He ushered in a new ugly norm in our country and I don't see that going away overnight. But if I were a betting man (which I am not) I would guess he'll tease a run only to make some lame excuse as to why he won't run, but only after making as much money as he can with the teasing.
