just updated to sequoia and activated filevault at start. cursor is showing but desktop is completely empty and cant do anything

i just updated like 3/4 hours ago and i've been trying to troubleshoot but in vain after updating to sequoia, my macbook pro asked me to activate or not filevault, for which i said yes. after that, i tried starting my mac. it asks me for my password, then black-screens for like half a second and then comes back to the loading bar. once the loading bar is finished, the mac goes to the desktop and shows absolutely nothing except for the empty desktop and the background. the mac seems to be working behind because if i click on f4 and then go to the top, i can see the cursor changing the writing thingy.

please can you help
