Libre Office Onenote
Starting a Microsoft Office for Windows application in Office Safe Mode can allow you to safely use it when it has encountered certain problems. This is useful when you need to open a file that you can't under normal mode because the application is crashing or if you need help in identifying an add-in or extension that may be causing a problem on startup.
How to start Office for Windows applications in Office Safe Mode
Collaborate for free with online versions of Microsoft Word, PowerPoint, Excel, and OneNote. Save documents, spreadsheets, and presentations online, in OneDrive. Share them with others and work together at the same time. Libreoffice does not have an equivalent to Onenote, but nobody says you should use only Libreoffice on your PC. Along with some of the very good alternatives already pointed out by Sardinha 94410 and muru, you may want to use a program with sync capabilities. In that case you should keep in mind that.

More Information
Automated safe mode
Automated safe mode is triggered if a Microsoft Office application could not start due to specific problems, such as an add-in or extension that won't start or a corrupted resource, file, registry, or template. A message is displayed to identify the problem and ask whether you want to disable the part of the application that has a problem. If problems opening the Office application continue to occur, automated safe mode may prompt you to disable more functionality that may be preventing the Office application from starting normally.
To view the list of disabled items, display the Disabled Items dialog box by doing the following in the Microsoft Office application that you're using:
Click the File tab.
Click Options.
Click Add-Ins.
On the Manage menu, click Disabled Items, and then click Go.
Note: You cannot view or change disabled items in Microsoft SharePoint Workspace.
After you view the items listed in the Disabled Items dialog box, you can select an item and then click Enable to turn it on again. Enabling some items might require that you reload or reinstall an add-in program or reopen a file. After you enable an item, the program might run into a problem the next time it starts. In this case, you are prompted to disable the item again.
Note: To stop Safe mode, exit the program then start it again normally.
