I accidentally converted my hard disk to dynamic then delete the volume again by accident.
After that, I convert it back to basic and run couple recovery software but none of it was able find my file.
Is there any other solution?

If you d-click HDD1 and HHD2 and expand the $Root, do you see your original file/folder structures?

FWIW, your drive is an SMR model. Some WD external HDDs support TRIM, but I don't know if internal models do.

In HDD1 (Which is the one I'm trying to recover) none of them is my original file but in HDD2 I can see all of them.
I just check it in CrytalDisk. It appears my HDD support TRIM.

TRIM Command Support for WD External Drives:
https://support-en.wd.com/app/answers/detail/a_id/25185

WD external SSD drives and WD external HDD drives that have SMR (Shingled Magnetic Recording) drive inside, offer TRIM command support which is enabled by default in Windows 7 and above, designed to maintain the performance of SSD or HDD at an optimal level over the lifetime of the drive.

TRIM command support on the USB (SCSI) side is called UNMAP and the controller performs an UNMAP to TRIM translation.

SMR drives need to rewrite the "shingles" during write operations. This can bog down the I/O, especially when the CMR cache has been filled. However, TRIM tells the drive that the data stored in the shingles is no longer needed, so this improves write performance.

I believe this is a very difficult case for the pros. I know of only one company that claims to be able to do this (Digilab, Chicago).

I could be wrong, so you would be advised to shop around.
I did some research and found out they could if they had the right tool but the data might be unuseable. Luckily that partition I used it just to install most of programs and games. Only a few of my works are there. Sadly my work that needs to be delivered by the end of next month is there. I had an older version of that work backed up on my GG drive. I could continue instantly if they weren't able to recover it.
