Endless OS 6.0.5 Firefox, gnucash, libreoffice-calc crashing

I posted this but on restart everything worked. I think it was X11 session instead of Wayland.

My Endless OS 6.0.5 was running fine till yesterday evening.
Firefox, gnucash, libreoffice-calc crashing.
I could open Chrome Browser and posting this.
Please help.
