Hi! Let me help you.
What was the last software you installed?
Can you please boot into safe mode to check if Explorer will crash there?
Press Windows + I to open Settings.
Go to System → Recovery.
Under Advanced startup, click Restart now.
Select Troubleshoot → Advanced options → Startup Settings → Restart.
After the PC restarts, press:
4 or F4 = Safe Mode
5 or F5 = Safe Mode with Networking
Choose either Safe Mode or Safe Mode with Networking.
