Hi! My name is Lui and will be happy to assist you today!
Please, check if the following steps solves this issue regarding Family account permissions:
>Go to C:\User folder, right click on the
folder with your username > Open the properties of the main user profile folder where the files are located (such as Documents, Pictures, etc) > Go to the Security tab and click Advanced > Check the box at the bottom of this window. It is labeled as "Replace all child object permissions with inheritable permissions from this object" and then click Ok.
Hope you find these troubleshooting steps useful and await for your feedback.
Best,
Lui N.
