XCode 13 - The application's Info.plist does not contain a valid CFBundleVersion

I'm trying to launch an old ios app in XCode 13, but it keeps giving me this error after failing to build it:

System Information

macOS Version 11.6 (Build 20G165)
Xcode 13.0 (19234) (Build 13A233)
Timestamp: 2021-10-06T08:33:19Z

I'm quite new to XCode so I'm not sure what to do. I Checked Info.plist and set my own build number to 3.

I just don't know what is the valid build version and where can I find it. I've seen similar issues where the build version number was missing but nothing that would talk about build version being invalid.

Setting $(CURRENT_PROJECT_VERSION) as the value for CFBundleVersion is the way to solve this issue.
