OS crashes for certain apps

[ashwin]

My knack says it's due to the app targeting Nougat/Oreo. Also, have you changed any setting in xposed modules?

i don't allow auto run at boot
I don't give all permissions in xprivacy

Yeah sounds like this could be the issue.

And those three apps, they require your location, phone info perhaps, and hence crash.

i don't think so
as I already have Ola installed and working fine. Upon update it causes issue 

Could you try clearing the specific apps data and update it?
