If you have no error messages, you should contact Tech Support.

I have had no problem using toolboxes developed in 2.9 being used in 3.0.  

It may be something other than the toolbox itself.

I found the problem, in my toolbox, one of geoprocessing tool that I used is (Convert Coordinate Notation), when the process passed by this tool, the problem happen an the ArcGIS Pro going to crash.

I used Inline technique ( %Folder% ), this is the real problem, I think Esri not fixed this issue.

The same problem happen with me when I using ArcGIS Pro 2.9, but when Esri update it to ArcGIS Pro 2.9.1, this problem fixed.

So, please @DanPatterson can you please notify Esri, to fix the problem of Inline technical issues in Model Builder.

Thanks in advance.

I'd also be sure you got everything in line with the new .NET requirements.  https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-6.0.5-windows-x64-insta...

I already install .NET, and my PC very powerful and meet all the requirements for ArcGIS Pro 3.0. But still not working my custom tool.
