We're performing changes on our download infrastructure. During this time, you may encounter downloads failing to complete or start. Thank you for your patience.
When it's still crashing try to delete StopThePed & UltimateBackup in the plugin folder. (That helped me aswell).
(The Screenshot shows my lspdfr.ini, maybe this helps you)
Download the newest LSPDFR Update --> lspdfr.ini and set "Main.DisableMultiplayerMap" to true
Edit: Main.DisableMultiplayerMap is not in the file included you have to copy and paste it
