When Jan fails to load a model, the process gets stuck in RAM but doesn't show up in Task Manager, leading to increasing memory usage with subsequent load attempts. This happens particularly when:

1. The Cortex addon is missing
2. User has restricted rights? (common in School/University settings)
3. Model loading fails but the process isn't properly terminated

Steps to Reproduce

1. Try to load a model with missing Cortex addon (or try with a computer in school as a student)
2. When model fails to load ("unloading model" message appears) > Try to load model again
3. Notice RAM usage increases but no process visible in Task Manager to kill
