System.ArgumentException: Could not find a datatype with identifier

If you have access to the database, maybe figure out what is trying to use the datatype with that id

SELECT * FROM cmsPropertyType WHERE dataTypeId = 1059;

Make sure to use .NET 8 with v13, .NET 9 might work but it’s not recommended.

Not sure if you’re using uSync or something like that, you might not have all your dependencies synced properly.
