Answers.Text: Yes, I too know that updating extensions is the way to go, but after the 5.44.0 upgrade I can no longer see my system status and have a blank screen. I'm not sure how to force the upgrade. I will read more about this. Thank you for your response!

You might have afform-admin installed. If you have access to the mysql database you can try `update civicrm_extension set is_active = 0 where full_name='org.civicrm.afform_admin';` to disable that extension so at least you can get to screens.
