Errors while using solve & other CAS functions in programs.

[Stunna_Snipz]

So I've been using the HP Prime for almost 2 years, and recently I seem to have lost the abilty to use some certain functions in programs, for example when I use the solve function in a CAS program it spits this out no matter what I do, I made this simple program to test that after resetting the calculator:

I've also tried different methods to solve this but I've come to no solid conclusions, And I'd be grateful if you were to provide help.
