"SafariBookmarksSyncAgent closes unexpectedly" It still appears and cannot open Safari

Yesterday I updated safari to 11.1 and since then the same message "SafariBookmarksSyncAgent has closed unexpectedly" has been appearing and just keeps coming back. I also cannot open Safari because "Safari cannot be opened due to a problem."

I receive the following error in the Safari application registry and SafariBookmarksSyncAgent:

Library not loaded:
/System/Library/PrivateFrameworks/Safari.framework/Versions/A/Safari

Referenced from:
/System/Library/CoreServices/SafariSupport.bundle/Contents/MacOS/SafariBookmarksSyncAgent
Reason: no suitable image was found.

What are some good open source alternatives for that?
