Nexus 5X crashing repeatedly on Oreo

I thought I had solved this but turns out it is now crashing again. My phone is a Nexus 5x

I updated OTA to Oreo about a week ago and today I changed some things. Suddenly I started crashing and sometimes the phone went into a loop trying to reboot where it just kept saying Google then rebooting but would finally pull out (thank you rescue party... I assume)

I noticed that it first started happening after an app multicon did some very odd things and then crashed. I started getting crashes ever 5-10 min in different apps and sometimes when the phone was just sitting there.

Since multicon runs all the time I got suspicious and cleared the cache (problem not fixed). Then I cleared data (still same problem). Finally I uninstalled the app. Since I did this the phone has not crashed yet (lasted about 4 hours).

I thought I had a solution but back to the same problem... argh
