R problem: tuning

Hi everyone, I have this problem with R. I'm trying to tune my tree but, when I run this code, the message in red appears. Then, my computer freezes and R just stops working. What can I do?

tune <- tune_tree(model = model, 
+                   cv = cv5, 
+                   grid = grid_tr,
+                   data = data)

[1] "This function temporarily loads the package 'party'."

Thank You!

What package are you using? Please include sessionInfo() output when you request help.

Thank you for your reply

That's what comes out

What can I do?

That is not the full output of sessionInfo(). Please include the full output.

Screen shots are usually not very useful. Copy the output and paste it here between
```

```

It is much easier to read and work with.
