Open collection is empty on startup

[AshkanArabim]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

When I open Bruno, the left sidebar shows the last collection that I had opened before closing the program. BUT, it's empty!

Trying to "open collection" (the same one) immediately tells me that "Collection is already opened".

I have to close the collection, then open it again from the collection directory to see the tests. This is an annoying behavior.

---- useful info ----
OS: Arch Linux
Bruno version: 1.32.0 (AppImage, taken from the GitHub release)
