This should probably be taken more as feedback than troubleshooting. The SDK is essentially unusable for me because it takes about 5 minutes after start before the GUI is unfrozen and after that I can’t really do anything because the cpu use is always maximum. I had to end the process in task manager just to close it after it froze for a long time trying to start a new project. Maybe on a faster cpu it is usable. On my cpu it is not. A program should not have cpu load in an idle state.
update to the latest stable version
