@Juan Rojas, Thanks for posting in Q&A.
According to your description, I know that you encounter a problem that when user login in, it appeared an empty desktop and you cannot do anything after windows11 update.
Based on my researching, I found that the issue is related to Windows, I have added Windows 11 tag.
You can also contact the Phone support in the following link to get help:
