i found same question on stackoverflow but that was about IntelliJ IDEA . and one question about android studio which had no answers!

i was using android studio 3.6 when this happened! then i updated to 3.6.1 and problem still exists!

then i downgraded to 3.5.3 and problem solved but this morning i woke up and see the same problem in 3.5.3 version too!

any help would be appreciatated.thanks
