Step-by-Step Fix
Update QuickBooks
Go to: Help → Update QuickBooks Desktop → Update Now. Install all available updates and restart QuickBooks.
Run QuickBooks File Doctor
Download QuickBooks Tool Hub. Open it → Company File Issues → Run QuickBooks File Doctor → Select your company file → Wait for scan to complete (up to 5 mins)
Copy File to Local Drive
If your company file is on a network or shared drive, copy it to your local C: drive. Try opening it from there. This rules out network path issues.
Check Folder Permissions

Disable Hosting on Workstations
On every computer EXCEPT your server: QuickBooks →File → Utilities → If you see 'Host Multi-User Access' click it to turn OFF. Only the main server should host the file.
Configure Firewall
Add QuickBooks as an exception: Control Panel → Windows Defender Firewall → Allow an app through firewall → Add QuickBooks Desktop
Restore a Backup
If nothing above works: File → Open or Restore Company → Restore a Backup Copy → Choose your most recent backup file
