[Bug] AppFlowy 0.9.9 crashes with 'too many open files' #8225
Description
Bug Description
I have installed AppFlowy via snap, flatpak, and finally deb/dpkg as after upgrading the snap the app crashes a lot. I was finally able to get a console output from the deb package and it gives me the following error:
...
