Controlled folder access blocks svchost.exe application

Yesterday I enabled controlled folder access in Microsoft Defender Antivirus (Update & Security > Windows Security > Virus & threat protection > Settings > Controlled folder access = On). Today every few minutes I get the message that svchost.exe tries to write in %userprofile%\Videos directory. Why does svchost.exe access %userprofile%\Videos directory, and is it safe to allow it to do this?

The message I get states that: "You can allow apps to access your protected folders, but you should only allow apps that you trust".

I have Windows 10 Pro version 2004.

Protected access prevents ransomware from encrypting your files. It blocked svchost.exe because "one of the svchost processes may be host to a 3rd party service, which Windows Security is not trustful of." See:
