Error while playing SSBM

[Anthem]

Hi,

So recently my friends have gotten me into playing melee on dolphin, but when i try to play with them online this error continues to pop up.

▶ /!\ An error occurred.

Line: 427
File: HW\EXI_DeviceIPL.cpp

I have no clue what's going on and I'd really love some assistance.

Thanks,
Anthem
