Hi,
Thanks for posting in Microsoft Q&A forum.
1,After a lot of search, I haven't found the document about number limitations. Per my experience, There are no hard-coded limitations.
2,As Configuration Manager version 2002 is out of lifecycle, it's recommended to upgrade to later version to have a try. Some known issue about application display in Configuration Manager version 2002 for your reference:
Applications were not seen in Softwarecenter
Application blade times out in Microsoft Endpoint Manager admin center
Best regards,
Simon
