Persistent 'Failed to Init sd card' on an Onn 128GB SD

I have an Onn 128GB MicroSD card (U3 A2 C10). It works without any issues on my Nintendo Switch Lite while in OFW, and the data transfer speed is quite good when moving a game from the NAND to the MicroSD. The problem occurs when trying to boot Hekate, as I get the 'Failed to init MicroSD' error message. After several attempts, Hekate boots showing the '1bit Mode' error. I thought the MicroSD was faulty, until I tried booting Hekate with the exact same MicroSD on a V1 Mariko with a PicoFly chip installed, where I saw that the MicroSD works perfectly—I ran the benchmark from Hekate and the speeds were as expected. Therefore, I can rule out a defective MicroSD, but the issue still persists on the Nintendo Switch Lite.
