Thanks for the video but, the 2 together last almost 3 minutes, is full of information and I don't know what I should expect in the results.
It would be better if you simplified the report to show only 1 problem with the minimum possible steps.
A video with a few seconds or the steps listed to reproduce the bug in the attached file.

Hey Abdelrahman!

weird cloth simulation cash bug for keeping the previous movment even if pins doesn't move (more about it in the video)

It seems that you've made a new report for this.

Please do the same for

noticed that I can not animate shrinking factor although it keyframe enabled

Also test 2.83 from https://builder.blender.org to see if it is resolved.
Cheers!
