I installed an eval version of ST 9.0.0 RC7 (64bit) on two separate machines.

On machine A, I can open and work with ST9, but when clicking File > Open, File > Save as, File > Export to Game.... whatever opens a file browser dialog, the application crashes.

On machine B, I can open ST9, but when selecting a example asset to open (or even when closing the initial Asset open dialog) the application crashes.

Thanks in advance for any hints on what to watch out for or try to resolve this!
