Poco F1 here. I'm running through a
major system breaking issue. I have no idea what's exactly causing it
I clean flash the ROM on a freshly formatted phone (fully formatted, incl. internal storage). Boot up, confirm my Mi account, complete the basic setup.
Then I click on the Google Play and add my Google account. All is good at this point.
Then I go into Setting and enable full screen gestures and AI optimization in MIUI Lab.
After a while, the phone slows to a crawl. If I don't reboot, it will completely lock up eventually, requiring a forced reboot.
After the reboot, it is seemingly good, but some stuff are broken, such as GMail (Can't view my inbox, crashes as soon as it displays it -- It consistently happens every flash), Google Chrome can't download files and I can't check for MIUI updates, because as soon as I click on the MIUI version, it closes. Repeating the operation gives me the option to see the logs, and here are they:

These logs are from the crash at the MIUI update window.

And these are from GMail.
It seems to be missing webview or something?
This issue doesn't happen on the other ROM which is based on xiaomi.eu, so I have no idea what's going on.

Here's a short 1-min video of this:

After a whole day of troubleshooting and testing different ROMs... I seemingly just had to uninstall the Webview updates and re-update it through Play Store...
hmm..
