1. Take Ownership of the file

The error can occur if ownership of the file changes. Therefore, you need to take ownership of the file to fix the issue.

• To do that, right-click on the folder you want to take ownership of (the folder that’s giving you trouble) and select Properties. Now, go to the Security tab and click Advanced. 
• From the Owner section, click Change. 
• Now, type your account name and click Check Names. Now, click Ok and then Apply > Ok.
• This way you will be able to take ownership of the file and hence fix the error.

2. Change the permission

The first method will solve the error in most cases, but if it doesn’t solve the issue, try changing the permission to fix it. You can follow the given steps to change the permission.

1. Right-click on the folder
2. Go to the Security tab, select your account, and click Edit
3. Check to Allow for Full Control and click Apply > Ok.

Now, check if it fixes the issue.

3. Check if the file is encrypted

If the file is encrypted, you need to have an encryption certificate to open the file. So, without wasting any time, check if the file is encrypted.

1. Right-click on the folder
2. Go to the General tab and click Advanced
3. Now, check the Compress or Encrypt attributes section and see if Encrypt contents to secure data is checked.
