Studio 2019 reverted back to trail version after activation and now cannot use license

I installed Studio 2019 on a new laptop. After deactivating my license on my old laptop, I activated it again on my new laptop. After restarting my new laptop, Studio 2019 says that I have to activate it again. However, my license is not valid as it says that it is already in use. But the licensed isn't used on my old laptop not my new laptop. How do I fix this?
