Fluent Academic version error
 

I can't start ANSYS Fluent Academic version, and the error messages in the console says:

The fl process could not be started.

version>
Error: There is no active application.
Error Object: (rp-var-value 'gpuapp/devices)

Error: There is no active application.
Error Object: (rp-var-value 'gpuapp/devices)

and when I try to close fluent, the error message keeps coming out like this:

Error: eval: unassigned variable
Error Object: rp-host?

I've tried running in admin and reinstalled multiple times, but I can't fix the error.
How can I fix this problem?
