SharePoint 2019 Suitebar is disappear and unable to correct it back
Where have you applied custom CSS/JS? Have you applied Alternative CSS from site settings? Try to find out it because that may cause issues for you later.
Try changing the master page of site to any of default master pages available. This might work for you.

ganeshsanap Thank you for your response.
I am not sure where did I edit the CSS/JS to hide the suite bar.
But I had use a default CSS file replace the environment CSS and I copy a default a master page to my environment. All this approaches are not able to bring the suite bar back.
Do you have any idea which JS file should be changed?
