I recently upgraded to a Samsung SSD 860 EVO 1TB

Everything was running smoothly until I booted up into a black screen. I looked up what to do and reset the nvram. After doing that my mac has consistently frozen at random moments. After freezing the computer will either restart, the screen will turn off black but the lights under the keyboard stay on, or turn off. Along with the freezing, my computer's battery has also been freezing and not showing correct percentage. I've done countless smc reboots and the problem goes away for a while but keeps coming back. I downloaded Macs Fan Control to see if the temperature was the cause but the mac will freeze no matter the temperature. I had previously been able to perform an apple diagnostics test and the results came back clear. But now I can no longer perform the test as the mac will always freeze before it ever finishes. The same goes for Recovery Mode. It also freezes during safe boot. I'm assuming it's the battery due to the high cycle count but not really sure. Any ideas would be appreciated.

I'm including an EtreCheck along with a Panic report(occurred while trying to use Recovery Mode)

I'm 99% certain it's the HDD SATA cable. Common point of failure on your model. Easy to replace. :)
