You do not really clarify what is the issue...

From the Terminal.app  Found in Application/Utilities, to see progress of FileVault, copy and paste:


sudo fdesetup status

To stop the process, copy and paste: (please note: your psswd will not echo)

sudo fdesetup disable 

If you disable FileVault in this manner reboot your Machine—

After restarting,  FileVault  continues the process of encrypting / decrypting.


You can see more info from the man page in terminal, copy and paste:

man fdesetup | more

To turn off FileVault, please refer to the section "Turn off FileVault" in the following article: Use FileVault to encrypt the startup disk on your Mac - Apple Support.

If FileVault was turned on - one must wait for it to finish the encryption process. Once that is done - it can be turned off as per previously suggested by @6x6
