Hi all, we have just upgrade to minor version as details below:

Old version:

        <PackageReference Include="EPiServer.Framework" Version="12.13.1" />
        <PackageReference Include="EPiServer.CMS.Core" Version="12.13.1" />
        <PackageReference Include="EPiServer.CMS.UI.Core" Version="12.17.1" />
        <PackageReference Include="EPiServer.Find.Cms" Version="14.2.4" />
        <PackageReference Include="EPiServer.CMS.AspNetCore.Routing" Version="12.13.1" />
        <PackageReference Include="EPiServer.CMS.AspNetCore.Templating" Version="12.13.1" />

New version:

<PackageReference Include="EPiServer.Framework" Version="12.19.0" />
<PackageReference Include="EPiServer.CMS.Core" Version="12.19.0" />
<PackageReference Include="EPiServer.CMS.UI.Core" Version="12.23.0" />
<PackageReference Include="EPiServer.Find.Cms" Version="14.2.4" />
<PackageReference Include="EPiServer.CMS.AspNetCore.Routing" Version="12.19.0" />
<PackageReference Include="EPiServer.CMS.AspNetCore.Templating" Version="12.19.0" />

After upgrading, we are facing a lot of exception regarding SQL, those exceptions were raised by both builtin schedule job (Search and Navigation indexing) and custom schedule jobs:

An exception occurred during reindex operation. System.AggregateException: One or more errors occurred. (A severe error occurred on the current command.  The results, if any, should be discarded.)
 ---> Microsoft.Data.SqlClient.SqlException (0x80131904): A severe error occurred on the current command.  The results, if any, should be discarded.

And we are also facing the issue on the async/awai or multiple threads code that use ContentLoader API :

 EPiServer.Framework.Cache.ObjectInstanceCacheExtensions[0]
      Failed to Read cacheKey = 'EPContentVersion:1616316_54892138'
      System.InvalidOperationException: ExecuteReader requires the command to have a transaction when the connection assigned to the command is in a pending local transaction.  The Transaction property of the command has not been initialized.

Do you have any idea?
