Stage manager can't be turned on.
Mac Studio, MacOS 14.5x. Recently discovered Stage Manager (SM). Quite useful. Had it configured and working well. Studio went down with a hard crash - as in hold on/off button for 15-20 sec. (I think Adobe apps (both current editions) maybe the root cause. Can't tell for sure.) Upon recovery I found that in the reboot nearly all preferences were erased. (Really Apple!?) All were eventually restored except Stage Manager. Have searched and followed every direction available at Apples 'help' sites. Yes, I've been to Settings -> Desktop&Dock -> Desktop and SM 3x times), nothing changes. The selection switch is always greyed out. Have done restarts, approached issue in settings and the Menu bar. The dock settings drop down does not have the SM as a selection.
So please experts, help me out here - an Do Not tell me to go to Apple's little help page. Been there, done that 3x times.
Thank you in advance
