In the Config menu, button dial setting, scren 2 set shutter AF-C to off fo both AE and AF

Setting "SHUTTER AF" (alongside "SHUTTER AE") is another piece of the puzzle, indeed, great observation, thanks - when both are set to OFF, half-pressing the shutter button in AF-C mode does not lock exposure anymore, which is now correct.

Turning either "SHUTTER AF" or "SHUTTER AE" to ON locks exposure again, which should depend on "SHUTTER AE" alone, not "SHUTTER AF", being a (recently introduced?) bug.

Then the AF is bone with the back button AF-L the bug us still present as what is shown but exposure is oerfect

remains wrong infos in EVF (and LCD) but the camera works perfectly this is while I did not notice the bug ....

Yet, I don`t have any issues with both "SHUTTER AE" and "SHUTTER AF" turned OFF and shutter button half-press, even EVF (and LCD) show the correct (non-locked) exposure But I admittedly didn`t use back-button focus, so there is no focus attempt at all (not being an issue for me if manual lens is used, though, but not a real option with an auto-focus lens, I guess).

And truly, like you said, trying with an auto-focus lens and back-button focus does show exposure (wrongly) locked in EVF/LCD again, yet once the image is taken it is actually exposed correctly (as if exposure was not locked, which is correct), so being different from what was shown on screen before taking the picture... eh.
