Ok, great - that's a bit better I guess. So are you using an ESP01 with the shim?
So that's using A2 and A3 for serial. You could try
A2.mode("input");A3.mode("input");and see if that helps at all?A0, A10 and A1 are also connected and you could try setting those to inputs.
That can always be a pain if yoy leave your meter in current measurement mode - I've lost track of the times I've done it :) but if you open it up there's usually a fuse inside that you can replace (because it is so common to do).
