Date modified has been changed after close Quick view in finder

I'm using Mac Big Sur (11.6) on Mac Mini M1.

If I don't open it with Ai before everthing is ok.

If I open Ai file before using quick view, I get something wrong the day modified of selected file is changed to current time, and I can't delete with by another program

I'm guessing you are accessing the files on an external or server?

This is a common Mac OS issue with remote (not local) storage.

Yes I'm access file storage on QNAP via AFP.

But I have a Mac mini runing with Intel chip, it's working normally. Two mac mini M1 I buyed have this problem

Its a Mac OS issue with AFP. Been happening for years with no solution from Apple.

The OS cannot sync with the file server properly causing issues with indexing (spotlight, dates, etc.) and file permissions.

This is why Adobe officially does not support opening files directly from a remote location.
