I totally agree, if possible, he would try to manipulate the election again. And, he has a VP in Vance who would not stand in his way, as well as possibly both houses of congress and some local and state election officials that would support him.
HOWEVER, there is one hopeful caveat. It is very clearly stated in the 22nd amendment that Trump would not be eligible to run again in 2028. So he would have have to find some mechanism to get around this. Granted, he has the Supreme Court in his pocket, but I am not sure they would go so far as to overturn a rule specifically and clearly stated in the Constitution. It is also very unlikely that enough states would ratify a new constitutional amendment to overturn the 22nd. So the only way I see that he could stay in power is to claim some national emergency and cancel or postpone the election. Even in our crazy political climate, I am not sure that would fly.
I think the more realistic danger is that he would manipulate the election process to install a handpicked successor (Vance on one of his kids??) to let Trump continue to run the country from behind the scenes.
