My 2012 Macbook Pro crashes or kernel panics when I plug it. to decrypt it's FileVault because it tells me to plug it in and when I plug it in the whole thing freezes and I have to hold the power button for like 5 seconds after the restart it only turns on without the charger or MagSafe Cable. Can anyone help?
Sounds like you probably have a failing hard drive in that laptop. While you may not have noticed the performance issues (or realized the cause of the performance issues), they were most likely from a failing drive. Decrypting the drive will stress a drive a lot so it put the drive over the cliff it was already on.
If you do not have a backup, then stop using this drive immediately and see if a professional data recovery service can perform a low level block for block clone of this hard drive so that you have an exact clone on a working hard drive. Then you may be able to install the clone drive & hope macOS will boot and allow you to finish decrypting the drive.
Unfortunately file repair utilities and at least the consumer level data recovery apps will not work on a drive which is in the process of encrypting or decrypting since the file system is in a very complex state at that point.
There is a slim chance you may have a bad internal hard drive SATA Cable which is very common with a 13" MBPro (mid-2012) model. You could try removing the drive & connecting it externally using a USB to SATA Adapter, drive dock, or enclosure and booting it externally.
FYI, if the hard drive is failing as I suspect, then the more you attempt to "fix" things the more likely the failure will be made even worse where even a professional data recovery service may be unable to clone the drive or recovery any data. You usually get only one chance to recover data from a failing hard drive so be careful & choose wisely.
It should have been possible to transfer data without needing to decrypt the drive.
If you don't have backups, then make sure you start backing up your new computer since there are a lot more new ways to permanently lose access to the data on the more recent Macs due to all the hardware, software, and security changes. Apple includes Time Machine backup software with every copy of macOS to make it easy for people to have backups....the user just needs to purchase an external drive.

On an Intel Mac I would try both
resetting the System Management Controller Reset the SMC of your Mac - Apple Support
resetting NVRAM/PRAM Reset NVRAM on your Mac - Apple Support
(get at least two-three rounds of the chimes when holding the NVRAM Reset)
no resolve—
A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
Kernal panics when I try decrypting the FileVault by plugging in the charger which means It will crash and not charge and I have to turn the MacBook off completely for it to charge, if I charge while it sleeps and open it it will crash and kernel panic, this problem started when I clicked the decrypt FileVault So I can transfer the data to a new hard drive.
and yes I did reset the PRAM with Command+Option+P+R It did not work
and I Can't Cancel it
it just tells me to plug it in to continue when I plug it in guess what it kernel panics
Mid 2012 Macbook Pro Crashes When i try to plug it in to Decrypt the Firevault.
