Deploying SP 2016 wsp to SP 2019 but resulting in error for Add-SP Solution

Question

I have tried to Deploy SP 2016 wsp to SP 2019 but that resul in error for Add-SP Solution Input string was not in correct format at line 1.

I have opened the SP 2016 wsp in VS 2017 in an environment with the SP 2019 installed. Also upgraded the solution when asked by VS 2017 to SP 2019.

It rebuild the wsp properly but not deploying.

Can anyone give me some idea on this?

Error which I am getting is:

Severity Code Description Project File Line Suppression State Error CS0433 The type 'SPList' exists in both 'Microsoft.SharePoint, Version=16.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' and 'Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' Bamboo.FullTextSearch C:\Bamboo\LT200\SPX.HW11.ListSearch\dev\Bamboo.AdvanceSearchSolnDual\Bamboo.FullTextSearch\Bamboo.SimpleSearchEngine.cs 48 Active

1) Check references in your project: Microsoft.SharePoint.

2) If there is a reference and it's not corrupted, check the version by opening library properties.

2.1) If you have referenced a newer version, add an assembly binding with bindingRedirect in app config, for example:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="Microsoft.SharePoint" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="15.0.0.0" newVersion="16.0.0.0" />
  </dependentAssembly>
</assemblyBinding>

3) Enable the Fusion log How to enable assembly bind failure logging (Fusion) in .NET and read the logs.
