Hi, this description of 'clean' shows that crucial information about your partitions has been destroyed - overwritten.
Clean vs Clean all in diskpart.. - [Solved] - Windows 7

Have you been using disk imaging routinely- which we repeatedly recommend? (e.g. Macrium Reflect (free - yes free) + external storage for disk image sets.

If you have, you can restore the most recent image.

(There are other disk imaging programs around too- it's been available for years as a method).

Hopefully you have a full backup of your personal data.

You can of course see what happens if you use data recovery or partition recovery programs such as
Rebuild and Recover Partition Table - EaseUS Partition Table Doctor

but I would assume the purpose of that command is to make that impossible.
