Homebrew working on Dolphin but not on actual hardware

Hello there, i'd like to start off saying i'm a complete beginner on the libogc toolchain and I apologize in advance if this is a dumb issue.
So i've been deving an homebrew app for the wii and making my way through the libogc toolchain with relative ease. My stuff is working on dolphin just fine and thats where I was testing it so far. Out of curiosity, i've tried launching it on an actual wii to see how well it would work, and unexpectedly, the homebrew gave me an SMPTE screen (the tv color test screens) and froze my wii. I thought this might just be an error on my code so I decided to compile and run one of the example homebrews instead (i've chosen the wiimote one, under devices/wiimotes). Same thing, dolphin runs it no problem but hardware cannot. I've also tried compiling other known homebrews to see if they would work, and same issue occured. My wii can run homebrew, i've used hb apps for a while. It specifically has issues with hbs that were compiled on my end.
I understand that this gives very little information about anything, so please let me know if you need any more infos / files from me. I would embed the dol file generated when compiling the wiimote test program, but unfortunately the website doesnt allow me to.
Note that i've already tried to switch sd cards, reinstall devkitpro entirely, run through the msys2 terminal so far.
