Troubleshooting • Re: PI4 SD cards only work in quirks mode

I wanted to know if this is a known hardware bug with the pi4 or if there is another way to fix it?
Not a known hardware bug. It sounds like you've got a SD extension or switch. Some of them have a 3.3V pullup resistor on one of the lines which breaks the 1.8V mode. The extension/switch will work on older Pi models because the SD controller doesn't support the high speed modes which require 1.8V operation.
It is a Sandisk ultra 32gb card that is directly connected to pi without an adapter.
I've also tested a intenso card and a no brand card that I got from a hardware store.

i've already tried updating the bootloader multiple times over the years but it didn't fix the issue.

It can still be an issue with the cards and not the pi. But it is weird that all of them have the same issue.
Are there any suggestions that I can use to further debug this issue?
