Windows 10 (Bootcamp) won't stay after sleep / hibernate

Hello,

I have a MacBook Air 13 inch 2017 where I installed Bootcamp with Windows 10. After a recent update, Windows won't "stay". If I reboot on Windows, and either:

• Close the laptop
• Select "SLEEP" on the power menu
• Select "HIBERNATE" on the power menu

and also, if more than 10 minutes pass, the laptop will NOT show what I had before in Windows. It will reboot, and show an apple logo with a progress bar just like if it had been recently updated (which it hasn't according to logs).

Does anyone experience something similar? Any clues on how to fix?

Thank you!
