Patch.obb could be extracted with 7-zip without problem.
Main.obb is an image file, just mount it with Imdisk/daemon tools/ or whatever program able to mount a virtual image and you can access to assets.

are you sure they are encrypted? as far I remember you just need to cut the header since it has some extrabytes, so that the files would start with UnityFS. Anyway upload some samples , I will take a look.

The header is UnityUnityFS so AssetStudio doesn't recognize it. Just delete the First Unity with and HEX editor and you will be able to load it . Since there are a lot of files I suggest you to automatize the byte cutting with VGMtoolbox

Here a guide thanks to Dj normality https://www.youtube.com/watch?v=o-rf4h41PS4

you could do it in 2 ways:

As the procedure of the video, you could set the string to search. In this case UNITY FS ,as the picture I attached shows, would be 556E6974794653 . So everything before it would be cut.

A second option would be set the lenght to cut at the start of each files, in this case 5 ( this works if every files has the same amount of extrabytes you wanna cut) .
