Have created a PR to help with this error: https://github.com/dolphin-emu/dolphin/pull/1878
The External Frame Buffer setting must be enabled for this PR to work. Either Virtual or Real is fine. The setting can be found in Dolphin's graphics settings, under Hacks.
A Windows test build can be downloaded here: https://dl.dolphin-emu.org/prs/pr-1878-dolphin-latest-x64.7z

Does the game actually crash or does it popup and then continue as if nothing happened? Also make sure it shows up in single core if possible.
I did some testing with v5.0-2577 and Baldurs Gate Dark Alliance. The error message pops up only if you have dual core option enabled. The error message dialog box has Yes and No button. If you click Yes, the game continues to run and nothing seems to be wrong but... I left the game running in background for a couple of hours and I got a bunch of error messages. First 2 were "FIFO is overflowed by gatherpipe!...".
3rd error message:
"GFX FIFO: Unknown Opcode (0x13 @ 0000000016CE680F, preprocess=false).
This means one of the following:
* The emulated GPU got desynced, disabling dual core can help
* Command stream corrupted by some spurious memory bug
* This really is an unknown opcode (unlikely)
* Some other sort of of bug"
4th error message:
"Illegal command 13
After I closed 4th error message the game seemed to be frozen and the screen was black.
