no sync

First can i point out I'm English UK not US believe me there is a big difference especially with spell check.

Since upgrading to windows 11 my personal one drive on my PC dose not sync with my online one drive and the copy that is automatically saved is to my online store and that copy is jumbled so i cant even copy it.

i let every thing set its self back up when i upgraded and before everything worked well not i cant even find any help in the system, it is very frustrating to keep loosing customers documents.

what do i do
