What issue do you have?
3 times this months, I lost all my notes in my "secondary app instance", on 2 different devices.
My setup:
I have a Nextcloud server with 2 separate Nextcloud accounts. (One for personal, one for work)
I use 2 Joplin instances: one for personal, one for work
In the past month, on 3 occasions, when I opened "Secondary app instance", I see an empty Joplin instance (I only see the tutorial "Welcome" notebook). Meanwhile, the notes in "primary app instance" are intact.
My issue happened 3 times, on 2 different computers. Every time it was always the "Secondary app instance" that lost data, even though on one device, that instance was connected to my personal Joplin (personal Nextcloud account) and on the other device, the "secondary instance" was connected to my Work Nextcloud account.
In other words:
Computer 1
Primary instance: Work
Secondary instance: Personal (lost)
Computer 2
Primary instance: Personal
Secondary instance: Work (lost)
In all cases, the Nextcloud server is intact. I just have to re-sync, but that takes quite a bit of time and it's annoying.
But was it really lost of just pointing at the wrong profile folder?
If you look under ~/.config/joplin-desktop, you'll see profile-* folders. Next time you lose the profile, maybe check to see if there are still folders and data in there

To be clear: I'm talking about "secondary app instance", not profiles. I don't use profiles anymore because I can't open both my work and my personal notes at the same time.
Right joplin-desktop-alt1 should have your second instance profile. If you close all instances and open them again, do the notes come back? I'm assuming it's somehow pointing at the wrong location although I haven't heard of such a bug before
