Sadly my slightly moribund Nephos setting is a bit more 1850s than 1750s.
You might like the Lord Darcy series - where technology has advanced to steam engines and the beginnings of electricity... in the 1970s.
One of the two main characters is a forensic sorcerer - specializing in medical examination.
Garret's reasoning was that the development of technology would be slowed by the advancement of magic - purely because the same kind of people were working on each. If Watt is working on spells to determine pressure then he is not spending time working on a steam engine.
And there were folks that did both.
I have an easier time with a divided effort slowing advancement.
In the real world it was the Church and state that tried to prevent the advancement of science - in particular the development of the crossbow. (Worked about as well as trying to tell the tide to retreat.)
On the flip side, the Pope of the time of Galileo was a Copernican himself - Galileo was not tried for trying to prove that the Earth goes around the Sun but... well, mostly for being a jerk. He wrote a work putting the Pope's words into the mouth of a character called The Simpleton.
Changing the charges to heresy was actually a way of letting him live - heresy is a crime of intent, and can be recanted.
