Repair a storage device in Disk Utility on Mac
Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional checks, and then checks each volume. If you run First Aid on a volume, Disk Utility verifies all the contents of that volume only.
If your Mac has a Fusion Drive and you see a flashing question mark or alert, see the troubleshooting section of the Apple Support article About Fusion Drive, a storage option for some Mac computers.
If you continue to have problems with your disk or it can’t be repaired, it may be physically damaged and need to be replaced. For information about servicing your Mac, see Find out how to service or repair your Mac.

Follow previous persons advise first.
Have you tried Manually downloading the Security Update 2020-005 and Stop there. Do a Time Machine Backup and then boot in Safe Mode - SHIFT - immediately at restart and then run the Security Update. This mode will eliminate all third party software, extensions and fonts from playing up.
Notation - There is yet another Security Update 2020-006 dated November 2020 - and appears to be last for High Sierra from Apple. Would suggest doing this one also from Safe Mode.
