WARDOGS support is investigating WD-L020 errors that stop some players from launching the game. The pinned support notice points to a possible compatibility problem with Windows 11 update KB5124010; it does not announce a completed fix.

The team describes its finding as a potential cause. Microsoft’s release page identifies KB5124010 as the September 22 preview update for Windows 11 versions 24H2 and 25H2. That confirms the update’s identity, not the cause of every WARDOGS launch failure.

Waiting for a repair is an option

Support says removing that particular update may allow the game to launch again. It presents rollback as optional, warns that Windows updates contain useful security, stability and compatibility improvements, and recommends waiting if you are uncomfortable removing it.

There is no repair date in the notice. Check whether KB5124010 is installed before assuming it explains your error, and follow the pinned thread for a confirmed solution.
