Note: Before we begin, please back up all data to an external hard drive. The following workaround is just one solution that worked for me and some other people, there is no guarantee that it’ll work for you. So proceed at your own risk. Once done, follow the steps.
1. Click on the finder icon and then go to the top menu bar. Click on Window > Go to Folder
2. Copy paste or manually type the following folder location.
/var/folders
3. A new folder will pop open, Inside that you’ll see several subfolders, each with a two-character name like ‘4v, hr, tv, zz‘ etc. This could be same or different for you.
Now according to the original poster, you need to drag all the subfolders except the one named “zz” to the Trash. Don’t delete the subfolder named “zz”. You’ll be prompted for your administrator login credentials.
However, in my case, I was not able to delete any folder except “hr”, and even that reappear once I delete it. But it still fixed the problem. I don’t know how, but just after that, I was able to open all the apps again.
4. Restart the computer and this will fix the messed up icons. You might have to log in to your browser and all the saved account once again, but that should be much of an issue, compared to what you just saw now.
