- If you have a major bug to report that has not been reported already, please take the following steps to report it to us. It will save you and our team quite some time. - Download the Matlog app from the Play Store. - Clear all previous logs and take the exact steps to produce the error you are receiving. - As soon as you receive the error (probably a force close), go straight into Matlog and stop the log recording. - Copy and paste the entire log either to Dogbin - Save the log, and copy and paste the link into the forum with a brief description of the error.
You need to patch the boot located inside the payload.bin file which is the rom. Not the recovery boot otherwise what you mentioned will be the result. I uploaded below. Patch this file with Magisk and you will be good to go.
