Right, so my phone died, I restarted it, got the sense home error and a com.google.process.gapps has stopped error repeating over each other.
I hit clear all data on Google Play services, this fixed the gapps error, but the sense home persisted, but only seemed to show up when I hit the home button. I cleared my HTC sense input cache and data to no avail. Then I google sense home to get to the store page for it, and thankfully there was an update available (otherwise I would have simply uninstalled/reinstalled). After updating I pressed home and still received the error, however I pressed open from the store page which brought me to themes or w/e. I downloaded some random Pokemon theme (didn't apply it) and pressed home. Totally worked. Took a little while for my apps and everything to appear again, but everything seems fine now.
I haven't installed anything for a bit but my phones been a bit wacky lately in general. For example the other day upon restarting after it died my phone decided to delete a seemingly random number of my contacts.
I think what made everything go haywire, however was after some restart when it started auto-updating apps which I had set to off for a good long while and had stored up a healthy supply of out dated apps. So I guess something in some update went ducky and upset my phone. Anyway, hopefully this helps someone and isn't just taking up space here. I'm on HTC m8 btw
