You might have better success to get someone to look at this, if you
also posted the FITS file in question. And also mentioning the issue ID
(which seems to be https://github.com/astropy/astropy/issues/7043).

I don't know any of the internals, but it seems to me that it is not
complaining about the ESO-style keyword naming but about the value of
the keyword, probably the lower-case 'e' of the floating-point exponent.
Maybe something to take up with ESO, if their software has written this
file.
