Obsidian and latte-dock - EMFILE error

I’m having this issue on 1st launch of the App after creating a Vault from scratch, there’s no way there are too many files in the vault.

Also, I’ve checked the file limits above and had the same output as @Abe

My vault path is not short /home/sam/Dropbox/sam/RefInfoPIM/ObsidianNotes ← is this any potential issue ?

Obsidian 0.13.19 under Ubuntu 20.04

TIA for any assistance.
