Unable to access meds menu or ping after being downed and revived

Not always but sometimes (possibly after being downed after being seer q'd) I can no longer access my meds menu holding down 4, I can use whatever med I have currently selected by tapping 4 but unable to change. Just had a thought while typing, I never tried selecting my meds via inventory but don't recall trying to access my inventory possibly also bugged, and yeh couldn't ping anything or access ping menu. Got downed again and revived again but no change
