I have got exactly the same problem as well. GPIO doesn't seem to be defined.

I found this thread. https://github.com/Bodmer/TFT_eSPI/issues/2628 It claims to have solved the problem recently. But what I understand is that is not in any official release yet. But read it for yourself.

Sorry my mistake, It has got nothing to do with MCUFRIEND_kbv.
