Screen locking when activating certain ults.

I have reported this a few months back, and it is still occurring. The screen will lock, (or unlock if you play with a locked screen,) with certain ults. The main ones I've noticed are jhin and ekko. Any functions in the option screen or unlock keys do not work, I've tried them all. The only way it resets to your original settings is to die with your champion. This bug is extremely irritating and has been around for months, with no sign of any rioters trying to address it.
