Character keeps falling

I have really annoying problem my player character keeps getting stuck on slopes and keeps falling if i jump on them…

to be more specific when character moves from stable ground to slope it get stuck.
similar effect when can walk off ledges is unselected.

but none of these issues happen in build version .
I have checked probably all character movement options but nothing.

I think there’s settings in Character / CharacterMovementComponent that define the maximum angle of slope the character can walk on.

i’s already maximum of 90 degrees and it wont explain why it works on debug build but on editor ?
