Why I can't export 4K UHD views on my student software? It always gives an error that Software did not have access to graphic hardware and them crashes.

I have installed a student version of the Twinmotion epic game launcher 2020. But it is not exporting 4K UHD views and videos as well as it crashes after showing an error that software does not have access to graphic hardware but in my settings, I have allowed this option for high performance. Please guide me about this issue. Thank you.
