When I pin a note Obsidian will hang. I am able to quit, but then the sync will hang loading the workspace. If remove the vault and resync, everything is good again. This is happening on multiple Macs. I updated to 1.4.5 via the new installer and the issue still occurs.
I am not sure what to try to see what is going on. Any help would be appreciated.
The pinned state is saved in the VAULT/.obsidian/workspace.json file.
Maybe have a look to see if you have duplicates of that? Moving or renaming it (and a restart) will reset your workspace and last opened files, but you could try that to start fresh and see if anything changes.
