BUG?: Automatically reset workspace

What I’m trying to do

After the latest version update, I found that after the reopening of obsidian, the workspace will be fully reset. That is, different from the workspace when exiting, all tabs have been lost and the ribbon has been readjusted.
Here is my debug inf:

Things I have tried

I haven’t found any effective solutions, but I think it’s rather a problem affecting the experience. It’s probably not a plug-in problem, because the plug-ins before and after the version update are the same, so I guess it’s probably the problem of the new version of obsidian.

I’d first guess it’s a cloud syncing problem. Do you sync your vault, and how?

If you look inside your .obsidian folder you might discover the workspace files are potentially duplicated or sync-conflicted.

Or do you store your vault on anything like a NAS or external hard drive?

Second, I would put any assumptions aside and test without plugins. But if the files are conflicted and you don’t fix them first, no other test might solve the problem.
