Help "XXX" has stopped unexpectedly...

[Android Question]

Hi,
My phone has been having some serious issues with software recently. I got my phone flashed twice by HTC service center to fix these software issues, but they keep coming back.
Basically, my phone's core apps stop working and I keep getting "XXX" has stopped unexpectedly... errors. Last time I got my phone flashed, almost all core apps had stopped working. My phone's keyboard kept crashing on load, so I got such errors every second.

Recently, google chrome kept crashing, so I disabled it and started using another browser (google chrome beta). But now, my andriod.com.settings keeps crashing, and I dont see a way around it. Here's the stack trace from the error report:
