Dev channel update to 91.0.831.1 is live

Importing favorites will be blank. This problem exists in 90.0.803.0 and later, but it has not been resolved, so I cannot use the importing favorites function and hope to fix it in the next version. Thank you! This is F12 data.
The system version I use: windwos7sp1 x64 Windows10 19042
