Hello,
Apology for delayed response.
- Do you get any error message/ error code while opening the folder?
I would suggest you to follow the methods given below and check if that helps.
Method 1: Perform Clean Boot.
Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. Check this issue in clean boot state.
Refer: How to perform a clean boot in Windows

Note: After clean boot troubleshooting step, follow the section "How to reset the computer to start as usual after troubleshooting with clean boot" in the provided link to return your computer to Normal startup mode.
If issue still persists try method 2.
Method 2: Disable security software temporarily
Disable security software temporarily and check if the issue persists.
Disclaimer: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.
Hope this information is helpful. Please do let us know if you need further assistance with Windows.
