The fix all for errors in Quickbooks is to clear my cache, clear all my history, cookies, etc. Then Quickbooks MAY start working again, but all my other software and functions no longer function and I spend hours solving all my other software issues on my computer, resetting passwords, etc. 

In this case, it cleared itself after about 30 minutes, telling me this wasn't an issue on my end, but an issue with Quickbooks itself. 

Probably this is the issue in most cases. Going through the "clear my cache" routine just gives Quickbooks time to fix there problems. The sad thing is, I went from Quickbooks Desktop 2014 in 2022,  that did everything I needed, to Quickbooks Online that performs poorly, all because the "outdated" 2014 version was the cause of my computer crashing. Now, with the latest, greatest Quickbooks has to offer, I still have issues with my computer crashing because of Quickbooks. 

So, I now spend $120 a month to deal with a poorly written software rather than live with the issues of Quickbooks Desktop 2014 that was already bought & paid for. I sure wish I had done more research here with users of Quickbooks Online.
