[VK84663]

I have a strange issue on my moto g3 (XT1550) after installing RR 9 official 19052019 ROM with pico gapps after some days I can't access the twrp, I mean when I'm booting on twrp it's only show the logo of twrp and then reboot the system.
Also the developers option not present in ROM or it disappeared.
Phone is non rooted.
Not able to reset phone.
Not able to change lock screen.
Anyone knows what's going on?

Fastboot boot twrp.img also can't boot recovery.
After fastboot -w command,
again flashed recovery and it booted but can't mount system, data & cache, showing invalid argument.
It solved by repairing file system.
Now working fine.
