Okay so I did what I said and I have a fix.
First of all, follow the instructions of Mock1010 :
1. rename "HoneySelect2_Data" to "HoneySelect2_Data.orig" or something similar
2. rename "HoneySelect2VR_Data" to "HoneySelect2_Data"
3. Launch HoneySelect2.exe, or use the launcher to start the main game
4. Rename HS2_BetterAA.dll to HS2_BetterAA.dl_ if it exists, or disable the plugin with KKManager.
Then, launch the KKManager and go to plugins. Disable all of those:

Unfortunately, the "extended save", "modding API" and "sideloader" are the ones making the game go to a white screen, but they are the plugins that allow most mods to work... That's why by disabling them, you have to disable all the plugins and mods that are depedent to them.
Now you should be able to launch a H scene! You will still have the white/blue-ish screen but only for a couple seconds so be patient and it will load up. If it takes more than 15 seconds, then something is not working.
Also, note that I have an issue with this fix: the skin of my girl is totally white and weird so there may be a plugin or two that are creating some bugs (because when I was turning the plugins on one by one, the graphics were okay and I didn't have this bug), you will have to try disabling some things until it works.
I'm just sad that most plugins don't work, it doesn't look as good and it lacks a lot of thing like the Uncensor, some make-up...
(PS: what is the purpose of the VR mod? Because when I launch a H scene, I can only watch the position that was automatically chosen and move the camera, but nothing else... Isn't there a way to have a menu and have more options like the normal game? If not, that was a lot of struggle for something really boring...)
