Faith following miracles

In the SD
peace,
I wanted to ask a question that I have seen almost no response to, if any.
Part of the religious argument is that miracles can serve as evidence of faith (even miracles of revelation), so the Jewish argument is that there were miracles in the Exodus, the sea was divided into 2(1) parts, there were ten plagues, and so on.
But despite all this, we did not see that the Egyptians repented and left their idols. Why? According to the Torah, in Egypt there were endless miracles, and the Jews were not harmed by them at all. For example, in a bloodbath, etc., to the point that even the Egyptian archeologists admitted that it was a miracle.
Therefore, the opposite question arises: if we know that the Egyptians did not change their faith following the Torah, isn’t this evidence that there were indeed no miracles in Egypt?
