KLWP remains blank

I just bought the pro version but when i set it up the screens remains black, even if i try again with other presets. I managed to make it work a couple of times but after a few minutes it crashed again.
I'm using a Redmi Note 4 with a Mediatek CPU
And nova, obviously
Thanks a lot in advance.

Please ensure you are on latest release, if you have Android 7.0 or later go in the settings and try disabling advanced rendering (its in the advanced section). If you still have issues please make it crash then collect a bug report as explained at https://kustom.rocks/debug and send me the file at [email protected] mentioning the issue.
