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.
