I have seen it already posted with no solution so I will post it again. When I start the application, every single time it freezes after a few seconds. If I click pull, the progress bar freezes, for instance. Everything becomes unresponsive, you cannot click anywhere. However, after a few seconds it all goes back to normal. Seems like the main thread is doing a blocking operation instead of delegating to worker threads for processing.

My source tree is the latest one today: 3.4.24.0. I am on this windows edition:

Edición Windows 11 Pro

Versión del sistema operativo 26100.4946
Experiencia Paquete de experiencia de características de Windows 1000.26100.197.0

The problem occurs to all of my peers, I am amazed that you haven't noticed yet. It is the most frustating thing ever. We are considering getting away from Atlassian just for this single bug.
