Hi,
From what I’ve seen in older threads, this looks like a glitch. After ending its process in Task Manager, try restarting the Windows Explorer process as well and see if that makes a difference.
If it still doesn’t work, have you tried using the PrtScn key as an alternative? Just go to Settings > Bluetooth & Devices > Keyboard, then turn on Use the Print Screen key to open screen capture and see if this one works.
