I've had this issue for months now and i have spent HOURS altogether watching YouTube videos and browsing multiple websites on how to fix this issue and absolutely nothing has worked. I've tried all the ways via gpedit.msc, regedit and entering commands. I've even tried deactivating windows and activating it again. I feel like my issue is very obscure and I cant find the cause of it for the life of me. I would be really appreciative if I could get some help. Keep in mind I only get this issue for desktop backround, my lockscreen backround works perfectly. Whats also unusual is that my backround at the moment isn't a default Windows wallpaper, its just a black colour. I attached what my error looks like below.
