The issue here is that this a regression, we worked with .NET 7 for a while with Aspose.Slides and now the new version introduced breaking changes that do not allow us to upgrade.
I beleive this is someting that needs to be prioritize regardless to Paid Support Service
We bought a license and wanted to upgrade to 23.3.
But we have the same runtime error on .Net 6
OS: Windows, error on 23.3 and on 23.2.
But 23.1 is ok, without this error.
We have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.
Issue ID(s): SLIDESNET-43878
You can obtain Paid Support Services if you need support on a priority basis, along with the direct access to our Paid Support management team.
