AzureDevOps Pipeline - UWP - Error APPX0002: Task 'GenerateAppInstallerFile' failed. Input string was not in a correct format

I have pipeline task whose YAML is as describe below:

steps:
- task: VSBuild@1
  displayName: 'Build solution **\*.sln'
  inputs:
    msbuildArgs: '/p:AppxBundlePlatforms="$(buildPlatform)" /p:AppxPackageDir="$(appxPackageDir)"  /p:AppxBundle=Always  /p:UapAppxPackageBuildMode=SideLoadOnly  /p:AppxPackageSigningEnabled=true /p:PackageCertificateThumbprint="$(signingCert.thumbprint)" /p:PackageCertificateKeyFile="$(mySecureFile.secureFilePath)" /p:PackageCertificatePassword="$(signingCert.password)" /p:GenerateAppInstallerFile=true  /p:AppInstallerUri="$(AppInstallerUri)"  /p:AppInstallerUpdateFrequency=1 /p:AppInstallerCheckForUpdateFrequency=OnApplicationRun'
    platform: x64
    configuration: '$(buildConfiguration)'
    clean: true
    restoreNugetPackages: true
    msbuildArchitecture: x64
    createLogFile: true

Basically here I am trying to create appbundle and generate the appinstaller file so I can distribute the app using the link as the app is an internal app.

This was working till 14th May absolutely fine. However when we are running the pipeline again it give us below error. I am sure AzureDevOps build must have been definitely update something in there agent. But not able to figure out the actual issue.
