Add All Browses to a tool by Right-click > Add All Browses OR Ctrl + Shift + B, then run the workflow.
The unhandled exception error is returned after the workflow is run.
In Designer 2019.1.4, there is a known issue where adding multiple browses to a tool simultaneously causes Designer to crash when the workflow is run. This is because when the Browse tools are added, the configuration is not finalized for each tool. A fix is being developed. In the meantime, please see the following workarounds.
Upgrade to the latest release of Alteryx Designer (≥2019.1.6).
Add all Browse tools one by one.
After adding Browse tools, save the workflow before running it.
Add All Browses with Right-click > Add All Browses OR Ctrl + Shift + B
Apply the configuration to each Browse tool individually.
Click each added Browse tool to open the Configuration window.
Click Apply (the check-mark in the bottom left corner of the Configuration window)
