Windows 10: Windows Security stops full scan because of exclusion

So I found an problem with Windows Security's full scan mode. While Windows Security is in Full scan mode, it had to stop the scan because of an exclusion. I don't know why this keeps happening. Why does this keep happening? How do I fix this issue? Thanks in advice!

Windows Security, Add an exclusion, Process

This link was helpful:

Configure exclusions for files opened by specific processes

When you add a process to the process exclusion list, Windows Defender Antivirus won't scan files opened by that process, no matter where the files are located. The process itself, however, will be scanned unless it has also been added to the file
exclusion list.

 

Windows Defender Antivirus Scan exclusions

If there is anything in Windows Defender Exclusion list, then it won't be scan and if it is malicious program, it won't detect.

It is better to remove all programs from exclusion list (if you didn't add them) and run a full system scan with Windows Defender.

 

Unable to add exclusion in Windows Security

Hello Paul.

Windows Version 1903 (OS Build 18362.836)

Controlled Folder Access is off.

Following your suggestion, Windows Security allowed me to add the folder as an exclusion, and I was then able to also add the file in question as an exclusion.

However, despite the file being listed under "Exclusions" it is still being deleted every time I copy it to the program's directory without any warnings or messages.
