have you tried a computer restart?
that can sometimes fix strange issues like this

Not wanting to jinx anything but I did a reboot and so far all is well!

I have got the same problem and found a solution: Change the script clearSafariCache.sh from

find /private/var/folders \! -name "*SafariTechnologyPreview*" -name "*com.apple.Safari*" -exec rm -r {} \;

to

find /private/var/folders \! -name "*SafariTechnologyPreview*" -name "*com.apple.Safari*" -exec rm -r {} \; 2>/dev/null

Because the original script throws "Permission denied" errors and therefore opens the file descriptor stderr, it seems that the parent process (com.apple.foundation.UserScriptService) can't close it as long as a file is open.

Thanks ralf!

I'll update the script to your solution.

This seems to be occurring with the App Store Cookie 5.12 under macOS 10.15.6 as well as earlier macOS versions. I see a gear icon appear in the menu bar. When I click on the gear icon, I see "clearSafariCache.sh Running" followed by "clearSafariCache.sh Failed". I've checked all the "fixes" in this thread and found that none apply to my situation. Any ideas?

I have this fixed in Cookie v6.0.17

@SweetP If your Cookie v6.0.17 fix works in Cookie 5.12, what would that fix be?

SweetP

Cookie 6 doesn’t use the script anymore as it’s not necessary on Mojave+

The clearSafariCache.sh script takes a very long time (almost three minutes) on my machines, too, so I went ahead and optimized the find expression a bit so it won't unnecessarily descend into huge directories like com.apple.metadata.mdworker.

Just replace the line

find /private/var/folders \! -name "*SafariTechnologyPreview*" -name "*com.apple.Safari*" -exec rm -r {} \; 2>/dev/null

with

exec 2>/dev/null
find /private/var/folders -name "*SafariTechnologyPreview*" -prune -o -name "com.apple.Safari*" -print0 -o -name "com.apple.*" -prune | xargs -0 rm -r

Now the script finishes in less than a second.

(I know that Cookie 6 and later do no longer use this script at all, but people who are still on older systems and cling to Cookie 5 might benefit.)
