Firstly Verify that your SQL Server edition is in the Enterprise Edition. If you have installed the Enterprise Edition, you shouldn't see evaluation period expiration messages.
also, check if your license is properly applied it sometimes happens due to this too.
If you're sure you have the correct edition and a valid license like I mentioned above, you may need to upgrade your SQL Server edition to the Enterprise Edition. Here's how you can do it:
Open SQL Server Installation Center.
Click on "Maintenance" on the left panel.
Choose "Edition Upgrade."
Follow the wizard to upgrade your edition to Enterprise.
kindly reboot your system after doing so and hopefully this gets fixed, do this one more time and if it still is the issue kindly raise the support req from the below link and someone from team will contact you soon.
Hope this helped if it helped kindly accept the answer thanks you very much.
