Not working for me. The local LLM is not giving any output?

I need some help to get it running,

I installed two local LLM, Gemma and Mistral. Both downloaded, but whatever I entered, there is not reply (it is emptly) from the local LLM. What could be the reason?

Also I am trying to find a data protection relevant use case to have the local LLM analyze and summarize a document. Is this already doable with this solution?
