Hi trinsonspaperm,

An error like this is triggered by random browser issues. We can do the basic browser troubleshooting steps to fix this.

To start, you'll want to sign in to QuickBooks using a private browser. This step disables its extensions and stops the cache from saving your browsing history.

• Google Chrome: Ctrl + Shift + N
• MS Edge and Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

If if you will not notice the error anymore, you can go back to your regular browser and clear its cache. If it still keeps on popping up, please try other browsers.

You can also do the browser health checkup as an added step.

Feel free to share an update after doing the steps above.
