Your post has been moved to a dedicated topic as the issue(s) you’re facing seem to have little to do with Manjaro updates, and everything to do with poor maintenance of your system.
To start with, please work your way through the Known Issues and Solutions section included with every Update Announcement.
Please provide system information as described (below).
I’m sure someone will help as soon as they are able.
Regards.
Update Announcements
The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.
System Information
While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes more indepth information is usually needed;
It’s best to ask your system directly. 
Output of the inxi command with appropriate parameters will achieve this (naturally, formatted according to forum requirements) and will generally be more useful for those wishing to help:
inxi --filter --verbosity=8
or the short form:
inxi -zv8
- inxi man pages (Arch Manual)
Be prepared to provide more information and outputs from other commands whenever asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.
