I have migrated a Mendix project from Mendix 4.4.4 to 5.21.2. After solving some java issues, I have no errors anymore. For styling I have used a theme from another project. I can login in the application, but after the login the index.html shows a white screen, what could be the problem? In the console there are no erros present.

Hi Remco try navigating to /index-console.html after you pass the login screen. A white screen usually is because of widget errors, which might be present after a major upgrade. Did you also try to update your custom widgets to the 5.x+ compatibility versions?
When you post your widget list, we can probably can give you some hints which one(s) might be the culprit(s).
After updating some widgets it's working fine.
