The apps that don't work are likely 32 bit apps. 32 bit apps do not work with Catalina. Contact the app developers and get their 64 bit upgrade if they have 64 bit upgrades. One example would be Microsoft Office 2011 is 32 bit. To run Microsoft Office on Catalina you need 64 bit Office 2019 or Office 365.
