When selecting the startup item again, press F8!
Next, select: windows system history restore!
Next, you can return to a certain point when the system is normal!
If it doesn't work, turn it on and press F8 to enter safe mode.
Use recovery tools, such as one-click recovery and recovery wizard, to recover.
If it doesn't work, reinstall it.
Here I recommend a system to the landlord: Twelve Constellation Studio!
