Plug-in error when launching in LightRoom Classic

I just upgraded the latest versions DxO PureRaw 2( V. 2.2.0) and Lightroom Classic (V. 12.0) on a Windows 10 computer.
When trying to use the plug-in, I get this error message: An error occured while launching the DxO PureRaw 2 plug-in.
PureRaw 2 was working fine before these updates.
Can anybody help me ?
