ClassLinker not found

- EdXposed Version: `0.5.2.2`
- Android Version: `9`
- Device Manufacturer: `Fairphone`
- Device Name: `2`
- EdXposed Manager Version: `4.6.2`

I installed Magisk, Riru and EdXposed all through the Magisk app on Android 9 without problems. I then installed EdXposed Manager and opened it but it only shows a white screen. Log shows this:

```
