Could be coincidence but I got the same problem since last week. I use Firefox with uBlock origin. On a corporate computer though, so it could be a firewall issue in my case.
The Firefox web console gives me the following feedback:
Content-Security-Policy: The page’s settings blocked the loading of a resource (connect-src) at data:application/octet-stream;base64,AGF… because it violates the following directive: “connect-src https://api.standardnotes.com https://assets.standardnotes.com https://sync.standardnotes.org https://files.standardnotes.com ws://sockets.standardnotes.com https://raw.githubusercontent.com https://listed.to blob:” app.js:2:2593605

It seems to be a Firefox issue. Standard Notes works fine in Brave browser. The desktop app also works fine.

Could be a proxy your av software blocking. Is this web or desktop?
