Y axis gets stuck sometimes

I have been using prusa i3 mk2s for almost a year. Recently i started getting layer shifts on y axis.
Layer shift usually occurs around 4 - 5th layer. I have tried reducing the print speed but no difference.
Belt tensions are okay.
Nothing restricting bed movement
When i remove the belt, bed moves fine without any hindrance.
Here are video links of bed movement:
1) Bed get stuck while moving with hand Q">

2) Printer Auto-Home correctly g">

3) Bed moves fine while operating from the control knob w">

4) Belt tension Q">

5) Bed moves smoothly when not connected to motor w">

Should not be using 3.8.1 on a MK2S.
