'Azure DevOps AssemblyInfo task errors with The specified version string does not conform to the required format - major[.minor[.build[.revision]]]

I'm trying to use the following Azure DevOps task in my build.

https://marketplace.visualstudio.com/items?itemName=bleddynrichards.Assembly-Info-Task

My task looks like this:

- task: Assembly-Info-NetCore@3
          inputs:
            Path: '$(Build.SourcesDirectory)'
            FileNames: '**/*.csproj'
            InsertAttributes: true
            FileEncoding: 'auto'
            WriteBOM: false
            VersionNumber: '1.0.$(Build.BuildNumber)'
            FileVersionNumber: '1.0.$(Build.BuildNumber)'
            PackageVersion: '1.0.$(Build.BuildNumber)'
            LogLevel: 'verbose'
            FailOnWarning: false
            DisableTelemetry: false

When the task runs, I see it works:

Assembly neutral language: 
Assembly version: 1.0.20220223.2
Assembly file version: 1.0.20220223.2
Informational version:

When I tried to build the app, I get the following error:

AssemblyInfo.cs(15,59): warning CS7035: The specified version string does not conform to the recommended format - major.minor.build.revision...specific csproj

There is a hard limit on the max size of each component of the version number for assemblyversion(possibly AssemblyFileVersion too), UInt16.MaxValue/65535, and anything above that will cause a compile error.

This is detailed here -> https://docs.microsoft.com/en-us/dotnet/api/system.reflection.assemblyversionattribute?view=net-6.0 in the remark section.

I had a similar thing and had to rework the build number format to get it to work.
