As you installed systemless xposed v86.1-sdk22-arm, you can uninstall it using Magisk Manager Recovery Tool V2.1 ALPHA by Pzqqt https://forum.xda-developers.com/attachment.php?attachmentid=4757812&d=1557687217
You should install this *.zip in TWRP and delete Magisk Xposed module.
Or you can use manual method: 'I'm gonna tell you how to UNINSTALL this if you've got stuck in a bootloop.'
For your own risk!
Ok noted with thanks. Will try it and get back to you
