Cannot get rid of "Tool not initialized" error

Question

I'm using linear regression tool for AI work. It suddenly stopped working 😲

The error is: `Error: Linear Regression (115): Tool #170: The input '#2' was not initialized.`.

I can't fix this error not matter what I do. Can someone please tell me how to fix this bug?

I added my Alteryx file as well. The input I'm using in Montreal bixi data: https://bixi.com/en/open-data/

This worked for me when I selected "duration_sec" as the target and the codes as the predictors. Then ran the model. It's not quick, due to the selections being discrete and the model picked.

Validity of the model is a different thing, as if this is for actual analyses, then some feature engineering would be recommended.

Note: showing the configuration of the tool would help in future.

By the way, one might think that the error is because some of the blocks have no connections, it's not the case unfortunately. The error is on the linear regression tool:

I have an exam coming up and I need this to work. I can try uninstalling and re-installing Alteryx but I'd like to know how to fix this in case this bug re-appears in the middle of the exam.
