RTAB-Map Freezes on 'Close Database'

[Kato]

Hello,

Recently, I have been trying RTAB-Map with a combination of Windows and Femto Bolt.
When I press the "Close Database" button to save the data, the application freezes and I have to force quit it.
Of course, the data is not saved.
What could be the problem?

I remember seeing a bug that Qt was crashing when trying to open a native Windows dialog. Which windows version are you using, and is it the latest rtabmap release? You may try RTABMap-0.21.0-win64-old_deps version, which use different versions of the dependencies.
