Run Apps .yxwz with error "Object reference not set to an instance of an object" in 2025

[TTMCarrieCai]

Run Apps .yxwz  file is good in Alteryx version 2024, but after install verison 2025.1, run the Apps .yxwz  file with error "Object reference not set to an instance of an object".

How to fix it in my computer?

Then I suggest a clean Alteryx reinstall.

Step 1. Uninstall Alteryx predictive & Alteryx.

Step 2. Navigate to appdata, delete the folders:
C:\Users\[user]\AppData\Roaming\Alteryx

C:\Users\[user]\AppData\Local\Alteryx

Step 3. Install Alteryx

Step 4. Install Alteryx predictive tools

Then test the flow again. Could be something the user configured or installed that accidentally broke something.

Let me know if this works :)
