What's the problem? Describe what went wrong in few words.
Dolphin freezes and does not connect WiiMote most of the time when "Refresh" is clicked. A Force Quit is usually needed to get out of the frozen app. Continuous scanning does not pick up WiiMote either.

What did you expect to happen instead?
Dolphin to not freeze and WiiMote to connect.

What steps will reproduce the problem?

1. Open Dolphin
2. Click Controller Settings
3. Click Refresh while holding SYNC on WiiMote

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-5283

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No
