MacBook Pro 2018 lid won't close

I have been working from home for 2+ months. The MacBook Pro stays open on a cooling pad , connecting to two Dell Monitors via USBC. 95% of the time the lid stays open. Suddenly yesterday I tried to close it but unable to do so. Feels like stuck at the position showing in the image.

I can’t see any clear signs of swollen battery . The battery cycle is only 118 and health is 91%. Apple website says my model is not eligible for the 15 inch MBP battery recall program. Mine was purchased on early 2018 during the release.

Called Apple support and it is useless but scheduled a service next Friday. I am now not sure if I should continue to use it until next Friday. But I may have to backup some data. Any help or knowledge will be much appreciated.
