Unable to Create the Cache. File or Directory is Corrupted and Unreadable. A damaged file system usually causes this issue. & since we’re talking about flash drives, it’s most likely NTFS or FAT. The flash drive can also be infected with viruses & malware, which is quite possible because of the portability of USB drives.
Bad sectors are another potential cause. Over time, these sectors become more & more damaged, & eventually, the file system simply can no longer get full access to files; these sectors interfere with it.
The last potential cause is the human factor; namely, inappropriate use of a flash drive & its incorrect removal from card readers. You can insecurely disconnect a USB drive for a long-time, but at any time it can be damaged. no one can avoid this forever.
That is why it’s so important to remove flash drives properly.
