Aha, ok also it's running and suddenly all is frozen.
Well, it can be anything ...
Check your PC with some software for benchmarking (stress test) and testing software in particular (CPU, RAM and so on). You may get some new infos in case it were something with hardware.
Also "PC Cleaner" - maybe it is something with settings or whatever
You may try Reaper. If it works properly, try Cubase trial version. Cubase seems to be more challenging.
If it still not works properly after all, i would like to contact Avid Support.
Good succeed !
