Maybe some conflicting libraries? I'm with you on the distaste for Arduino,
mainly from the dependency/library management which is next to non
existent. PlatformIO is a little better, and support all the Arduino
boards, but can be overkill.

You could try renaming the Arduino folder (In documents on Windows, not
sure on other platforms), and installing the esp platform and libraries
from scratch in case there's a conflict. A somewhat nuclear option, but
quicker than picking through libraries one by one. This is assuming you
already had Arduino IDE set up previously, if you set it up from scratch
just for this, then lib conflicts is unlikely to be the issue.

Also, could you post up the exact error or a screenshot? Some of these libs
pop up warnings in the console that look like errors but can be safely
ignored. Can't quite tell with this one.
