Okay, I solved it. After searching around and trying lots of different stuff it finally came to an end.
I wrote in the original question that "all my drivers are up to date", which, looks like it was a jerk lie coming from me. I apologize for that, I updated only the firmware and had visions of updating the driver as well.
Enough with the excuses, everything was solved by installing the latest driver from the original site of Samsung.
The driver I had before was, as shown in the tool "Samsung Magician" under the NVMe Driver, owned by Microsoft. After installing the Driver, it shows Samsung.
I again apologize for the misinformation, and I thank Brent Ozar for the support, which without, I would've long abandoned this quest and would've just "dealt with it".
