After updating the LA portable version, it won't start.

I believe the script files from QM and the script files in LA have the following relationship.
Portable.qml == files + files.xml

I still don't understand why they need to be forcibly replaced files + files.xml

The migration settings of the QM portable version, as shown in the image below, are much clearer.

Regarding the migration of the DLL folder:  
The files in the .nuget folder of the installed version of LA are too large, so I manually copied the DLL files downloaded by NuGet to the DLL folder (as the DLL updates are not too frequent). Therefore, I need to migrate this folder.
