Extract will store default as temp and it missed then tableau will ask you to find the extract. Better locate the extract and go to saved extract and select.
I also tried to locate the particular temp file TEMP_0*** from the given path and didn't find it.
Regenerate the extract once and check.
I tried that two times ago hoping it wouldn't recur, but even after all the wait, unfortunately, it happened again and again after some time. I'll still regenerate it, though it'll probably recur after a while.
