P44pro Sequential writes are unusually slow

[alien]

 

Today, when I was copying a large number of files, I found that the writing speed of the p44pro was very slow.

Then I used CrystalDiskMark 8 to test it, and the sequential writing speed was only 2000MB/s.

I tried restarting and manually optimizing trim but it couldn't be solved.
I need help.

ps.Other ssd works fine, win11 23h2

Same exact problem.
The only way to get back to the declared speed is formatting. But after a few months the speed disappears. Has anyone solved it?
It seems that the support doesn't care since all the time they don't communicate anything, the usual pre-compiled answers
