This looks a lot like:, so I’ll copy the findings here: 

Could you do the following: 

Go to your Mendix\<version>\modeler folder, then find the studiopro.exe.nlog file, and then change the minlevel to "Trace" (or "Debug"). 

Afterward, you would need to reproduce the issue again (so: run the app again) to get all the logs.

Possibly, you’ll find logs like: 

<!-- 0 0 174 0 1649078789 4 --> ---> System.Net.WebException: The remote server returned an error: (403) Forbidden. at System.Net.HttpWebRequest.GetResponse()

If so, the issue is that Studio Pro uses the proxy to call To handle it, just add or update the environment variable NO_PROXY to add, after it should work. 

If not, could you please share the logs here?
