```

**To Reproduce**
1. I created a console project using .NET 7
2. I added a ML scenario for "Text Classification"
3. I added my CSV data (only 10 rows)
4. I selected the columns
5. I clicked on "Train"
6. A popup appears showing me the training time etc. looks all good
7. Exception occurs

**Expected behavior**
I expect to proceed to "Evaluate" step. If I manually go to this tab and press the "Predict" button, I get the same exception as above.

**Screenshots**

**Additional context**
Last log entry in VS is `Generate code behind files`
