Hello @JayDee23,

The biggest issue is that you need to follow the instructions mentioned on Page 167 of the user guide (below) to do Uninstallation of SAE 2.x Linux
https://topics-cdn.dell.com/pdf/supportassist-enterprise-v20_users-guide2_en-us.pdf

It is not advised to delete files manually to uninstall SAE.
SAE should be in corrupt state now, as SAE related files have been manually deleted/removed.

Please follow below steps and update us.

• Log into SAE Linux server using Putty
• Does below folder structure exists in customer environment?
  /opt/dell/supportassist/bin
• Run below command and share the putty screenshot
  rpm -qa | grep supportassist

Best regards.
