for context: I have an Asrock b450m/ac R2.0 MoBo (that seems to matter), and I’m running Nobara Linux. I was using OpenRGB to control some rgb fans and it was working fine, although I couldn’t control the individual LEDs. Then suddenly (Can’t think of anything I did that would’ve messed it up, other than maybe going from the ‘effects’ tab (from the plugin) to the default one, and clicking apply color, that’s when it happened) it stopped recognizing my devices. I read online that I needed to run it as sudo, but when I do, I get this error

Attempting to connect to local OpenRGB server.
Connection attempt failed
Local OpenRGB server unavailable.
Running standalone.
[i2c_smbus_linux] Failed to read i2c device PCI device ID
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

From looking online it seemed to be the SMBus access problem mentioned in the OpenRGB Docs, and so I tried following these steps, but honestly I think I’m too new to really understand how to do it right. It felt like things kept going wrong during the patching of the kernel part, up until the last line, which simply didn’t work.

As a Linux noob, I would super appreciate very noob friendly responses. Any help would be really appreciated.
