Custom Python Toolbox Crashes Pro on 2nd Run after upgrading to 3.5

[KonradBostrom]

I've recently upgraded Pro from 3.0.3 to 3.5.2, and several of my Custom Python Toolboxes will now crash Pro if I run them a second time in a row. The tool works as expected, if I close and reopen Pro before running it again, but this isn't an issue I had on 3.0.3.

My code and input data are unchanged.

I'm curious if anyone else has experienced this behavior or has any insight into what might be causing this.

Thanks!

Rewriting my toolbox and removing all opensource / non-default modules stopped it from crashing on rerun.

Glad this solved the issue.
Unfortunately rewriting all toolboxes within our company is no viable option.
On further research I found another BUG that also mentions geopandas: BUG-000151279 for ArcGIS Pro
Maybe @Robert_LeClair can forward that information, so the issue might be fixed in 3.7 or any following patches/hotfixes.

@KoryKramer - does the ArcGIS Pro Dev Team know about this item/issue?
