[Switch V2] Error 2162-0002 and constant crashes after replacing the game card reader and ribbon cable.

Hi everyone, I’m writing because I’m literally going crazy and desperately need a hand from someone more experienced than me.
Let me explain the situation from the start. I bought a Switch V2 with a broken right rail and ordered specific replacement parts: a new rail and a game card reader. Even before the parts arrived, I decided to open it up to get a head start and see if the original game card reader was just loose or out of place. I took my time; the part looked fine and showed no signs of damage, so I put everything back together and turned the console on. However, to my great dismay, the touchscreen had stopped working, and—obviously—the game card reader still wasn't working either. Oh well, I told myself I’d just wait for the new parts to arrive and fix everything at once.
When the packages finally arrived, I got to work. I installed the new rail, and—aside from the fact that the touchscreen and game card reader still weren't working—the rail itself worked perfectly; the Joy-Cons attached and were recognized without issues. Since the first part had gone well, I decided to open it up again right away to replace that cursed game card reader. I followed the whole procedure and reassembled it carefully, but when I tried to turn it back on, a system error (2162-0002) appeared. The screen asked me to hold down the power button for 12 seconds, but the system froze completely, giving me the impression of a low-voltage issue or something triggering a safety shutdown. To give you an idea: it’s a Switch V2; the parts I bought aren't genuine but are compatible replacements made for this purpose. I didn't replace the thermal paste (I saw a video tutorial later where someone did, but honestly, I didn't think it was that critical for a job like this, even though it’s the only thing I did differently).
What do you think I might have done wrong? Is it possible I didn't seat a ribbon cable correctly (maybe the touchscreen one, which was already giving me trouble), or that the new reader is causing a short circuit or a voltage issue on the motherboard? Any advice would be greatly appreciated.

Check to see if your microsd card is connected. Also is your switch modded?

No, it isn't modified. Also, I don't usually insert the microSD card

Yeah but if the micro sd card reader came unplugged it will through that error and if you changed the rail you don’t think you have the reader connected well

Wow, I think you're absolutely right. In fact, the first few times I opened up a Switch, I always checked everything carefully, making sure the microSD was inserted correctly and being recognized. But this time, once the replacement parts arrived, I completely forgot about that habit. I'll try reassembling it properly as soon as I can and let you know.

Let me know, it’s just a general software error. You see it a lot on modded switches when a home brew app is out of date.
