You'll need to reinstall your QuickBooks program and update your QuickBooks server, abconstr.
SIAB is correct, this issue is not related to Intuit's system since your QuickBooks Desktop (QBDT) version 2021 has been discontinued and should not have received any updates.
Before reinstalling, I recommend creating a backup copy of your company file. Then, you can reinstall your QBDT program. Once done, update your QuickBooks server. Here's how:
- Go to QuickBooks [year] Server next to the Apple logo.
- Select Check for Quickbooks Server updates.
- Click Install Update.
- Hit Install and Relaunch.
