Menu bar is waiting for its definition, which is being loaded from the disk.

But the main problem is corrupted installation of the IDE. There is a lot of messages in the IDE Log, so a lot of data needs to be written to the disk, which makes disk access very slow. Furthermore, the USB disk can be quite slow even under normal conditions.

Please check the log, fix your installation (you might need to clean your userdir), and try it again.
