Then it sounds like this issue: https://bugs.dolphin-emu.org/issues/9044
There is no known solution, but it's nice that you managed to find the workaround of mounting the disc. I don't think anyone has thought about that before, because mounting a disc when using Dolphin is not useful in most other cases.
