If you do it manually, does it work?
Do you see any error messages in this context?
And is there any message about this under Tools > Site Health?

Unfortunately, your post is formatted in a way that makes it difficult to read. Do I understand correctly that in Tools > Site Health you see the message

No access to file system

in Tools > Site Health? Then there is something wrong with your hosting. File and directory permissions do not seem to be set correctly. As a result, WordPress cannot install updates, no matter what.
