Stuck on the second screen(MIUI)

[KateWasHere001]

hi,
I just tried to compile the source. After flashing, I found that the system stuck on the second screen, that is, MIUI appeared, the Zygote process exits through the logcat log. The following is the specific error log context. Please help, and how to make it right to start os normally.
