SSD space disappeared after partition. help!

In Disk Utility, choose "Show all devices" from the View popup menu.

Select the SSD Device and see if the Partition button shows the two parts.

If so, see if you can remove the second one, then merge the first container into the free space.

Note that if there was any data on that second partition you made, it is now gone forever short of paying a company a lot of money to recover it.

Here is the Guide for how Disk Utility handles partitions: Partition a physical disk in Disk Utility on Mac - Apple Support

Out of curiosity, why did you use a third-party tool instead of BootCamp? What features does it tout that makes it a better choice than Apple's tools?

It is here you reformat the drive not the Container, or child Volume level as GUID/APFS

What happens when you click on the Partition button?

The article I linked should explain how to merge the partitions together.

I was using Paragon Hard disk manager because I used it to backup previous BOOTCAMP volumes.

Seems like a bad reason, given the results.
