RPi5 w/ Pironman 5 can't boot

Hi all. I just got my Pironman 5 with an RPi 5, and I’ve been unable to boot it at all. I followed instructions to the letter, flashing the bootloader works fine, I get the green screen, but it won’t boot from either the NVMe or SD card (I reflashed the bootloader for SD boot when trying the SD card). I tried removing EVERYTHING from the Pi and only leaving the SD card in, and the result is completely identical, 3 long LED blinks followed by 3 quick ones, according to this article, that indicates an I2C issue, but this made no sense to me as it should’ve (in theory) worked with just the SD card. Any help is highly appreciated, I tried looking through the forums (both this one and the official RPi one) and I was unable to find any duplicates, sorry if I missed something

Can you try to boot Rpi5 itself without Pironman5. Just to isolate the problem. If it’s ok, plug one piece at the time and try to boot, until the issue is there.

I was having trouble getting past the Welcome to RP OS screen. I switched SD cards and it worked for me

As mentioned, I tried it with JUST the SD card, by that I mean no pironman included accessories, pi itself, SD card, and a power cable
