You can download and reinstall Obsidian 1.1.6 from https://github.com/obsidianmd/obsidian-releases/releases and rely on the internal update method (it does not update electron but just the core app).
As long as it works, fine, but we are not going it accept bug reports against this version and at some point something will break. When that day comes, please don’t post another rant here. We got the memo already.
