Question StarGo Align tab vanishes

I own a Linear Fast Reverse mount since 2016 and I have been working with StarGo with no big issues so far. Recently I upgraded The StarGo to vers. 6.2.0 SP3 and the surprise is that sometimes (not always) when I park de mount the ALIGN tab vanishes from the app. From this point, there is no way to do anything, just close StarGo and run it again.
See the attached image.

Hi Stefano,
I have reinstalled StarGo as indicated, but the problem persists.
The issue does not always arise, but it does in the process of polar alignment with Polemaster. The workflow is as follows:
I run StarGo, sync the mount and minimize the global StarGo screen popping up the virtual keyboard pad panel. When executing the Polemaster process, I try to move the mount twice a little more than 30 degrees. I close the virtual key pad panel and the main StarGo screen is displayed again in order to rotate the mount to the home position. Next, I minimize the StarGo main screen for greater visibility on the polar adjustment screen showing the virtual key pad panel again. After polar alignment is complete if I close the virtual keyboard, the main StarGo panel appears without the Align tab.
Once reinitiated the StarGo, everything runs perfectly for the whole night.
Hope this may help.
