Well, here is the thing.
The ONLY place in the world that mentions the 10 plagues is the bible, There is NO historical mention other than that. It's MADE UP!
Just ask yourself this.
Here you have the World Power devastated by plagues, has every 1st born male killed, has its ENTIRE army and King slaughtered at one time, and lost all its slaves. It is now completely defenseless, not for days or months, but it would be for decades most likely,
And there is NO mention of it by any of the nations around it?
Not one nation thought - wow - here is our chance to swoop in and take all the riches of of Egypt?????
There is NO chance it ever happened.
