[Solved] Cannot Save New Files

When I make a new file on Open Office 4.1.6 on Windows 10 I cannot save the file using any method. I can save edits to existing Open Office files, but I cannot use the 'save as' option for existing files. No error message occurs when I try to save, nothing changes onscreen at all. I can make new files only by duplicating old files, deleting the text, rewriting it and then renaming it. This began after installing updates. Looking at other threads on this topic, I successfully renamed the user profile but it did not help. I rebooted the PC in safe mode and that did not help either.
