My disk D crashed

[shrewd river]

Please help me, I installed dual boot on Windows and Arch Linux. I probably did something wrong, and now I don't have a D drive. It's visible, but I can't do anything with it

It did not crash

That partition has a filesystem which windows can't read

like ext4 or btrfs which are linux filesystems

So you likely deleted/replaced/formatted the wrong partition if you had data on there
