The Xposed installer is just an app and doesn't conflict with anything. You didn't specify anything about how you're trying to install Xposed or what package/version you tried.
As Klaus said, flash via recovery (if you haven't) and make sure you use the right zip. I use v87 on Lollipop and all is good.
Coincidentally, on another phone, I installed a Nougat ROM (LOS-based) along with Xposed and got the same behavior. Trebuchet was crashing and then everything else. I think some permissions got hosed somewhere. Dirty flashed the ROM and made sure everything worked. Then went back and flashed Xposed. All good.
