... how so? And the error message, if any, is...?

Apps are not working properly. Sometimes not opening. Sometimes crashes.

This is meaningless and way too much confusion...

Also you already opened a thread for the same thing.

"Apps are not working properly"... Which ones and how are they working or not, exactly? Error messages, etc. In a nutshell the same as in all of your threads. Also some software not working is independent of the tool that installed it which is another softwasre that can have its own issues.

"Sometimes not opening. Sometimes crashes."... You can't be more vague that this. Just don't.

Please avoid opening thread like this, as commented before. You're just wasting your time (and now mine) to go nowehere. I've probably written more already just replying to your threads and telling you what information you should give along with a proper description of the problem than I would have to do to actually solved any issue. And, of course, this has nothing to do with Linux. Try doing the same in any Windows forum and you'll be suspended or banned in no time.
