Don't know what else to try.
mornin tannenba.
thx friend. ..just last night I was talkin to a young person that posted on r/ who was showin off a very pretty 1200 fresh off the floor, had that mystichrome, or whatever hd calls it, paint.. not sure I recall the big sportys looking so fantastic. ..what exactly is that gold dresser in your profile pik?
so, just how long have you been running win 11.. sounds like your os is a lil wonky, refusing a restore is spooky... like a ghost in the machine.. depending on the associated chores in regard to personal files and apps a system reset may be in order.
reckon as admin going through the settings and unlocking the things to have a peek about is a thing, consider what else you may have done / acquired at time you did update and noted change.
from the nature of what you describe I would lean towards verify via speed test your internet to rule out issue, or at least isolate possible hardware cause.
go through the OneDrive settings real thorough. it is a funny thing, depending on what other hardware you have and have synced and what av protection you use.
I recall tuning the onedrive to mostly be concerned with system snaps and its relationship with defender and less concerned with my files and the sync of the other devices that share it to be quite a bit of chores.
my internet is primitive at best and often suffers due to geography so I must tend to just how the things use it.
your system is not only fetching an image when you choose save it is caching it so it can cloud it and the other goofy background things anticipating you interacting the image with viewer or edit believe it or not.
...which brings up diagnosing with the sys monitor what all is going on at the point you request the save and during the delay till it initiates the save.
then there is also the update itself, could be by now this is not an isolated thing and a known issue by now.
All good on ya
