Unable to select a folder for creating the very first graph

On launching LogSeq it shows a tutorial graph. It then asks to select a folder to create a new graph at the end of the tutorial.

However I am unable to select a folder to start a new graph. The application does nothing and takes me back to the select folder screen.

Relevant Logs:

This issue only occurs if I install logseq via flatpak. I compiled the application from source and it was able to access disk for creating a new graph.
Also worth noting that once it worked with the compiled app, it started working with the flatpak installed app as well.

I added an [issue on the logseq repo](https://github.com/logseq/logseq/issues/7507), I was redirected here. It seems like flatpak installation is not getting correct permissions.
