Body: <p>Just upgraded to CiviCRM 5.65.1 and now when I open contacts who I know have contributions, the tab shows the number of contributions, but the box below the tab that should list the contributions is blank and I get an error:

  <p>The contributions show up in the Activities tab instead.</p>
  <p>Anyone else having this problem?</p>
  <p>Also I dug around in my PHP error log and found these two critical errors:</p>

ThreadText: # After CiviCRM 5.65.1 upgrade, Contributions tab is blank but contributions show up in Activities tab
  
  (Asked by: username_0 on 2023-09-14)
  
  Just upgraded to CiviCRM 5.65.1 and now when I open contacts who I know have contributions, the tab shows the number of contributions, but the box below the tab that should list the contributions is blank and I get an error:
  "Unable to reach the server. Please refresh this page in your browser and try again."
  
  The contributions show up in the Activities tab instead.
  
  Anyone else having this problem?
  
  Also I dug around in my PHP error log and found these two critical errors:
