I used to flash dirty flash with TWRP and update from Fastboot both before, but it got the same situation: The Google and Webview crashed, WiFi did not work, SIM card couldn't unlock in 11.19dev.
So I dirty flashback to 11.8dev, and everything worked well
Then I saw somebody said you can try to clean the Dalvik/ART cache and cache before you reboot after flashed in Recovery, So I tried with that, and I got this situation: The WiFi is working, the SIM card working, Google crashed, Webview crashed and Xiaomi Account crashed, then I try to clean data of these apps and re-install the APP that getting force close such as WeChat. Right now every APP works well expected Google Pay.
