Add trusted location via reg file unsuccessfully.

@Vu Nguyen ,
Welcome to Q&A forum!

In the registry, the key value that defines the system variable path %UserProfile% is different from the regular path.

If you add the KTVP folder as a trusted location through a .reg file, please change the path to "C:\Users\Administrator\Desktop\KTVP". You could right-click the KTVP folder, and then click Properties to view its specific location. Then double-click the .reg file to run this registry.

Windows Registry Editor Version 5.00  
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Excel\Security\Trusted Locations\Location9]  
"Description"="KTVP Doc entry file"  
"Path"="C:\\Users\\Administrator\\Desktop\\KTVP"  
"Date"="13/07/2021 06:58 PM"  

It is displayed in the registry as shown below:

If you want use the "%UserProfile%\Desktop\KTVP" path, please add the following key value in Registry Editor directly and use Expandable String Value to define the folder path as shown below.
