Big Sur Install Stuck

The progress bar hasn't moved in over 24hrs. I've already turned off and restarted it, no change. Please help.

Shutdown and disconnect all external devices. Restart and immediately hold Shift until the Apple Logo is presented and then release. Safe Mode will do a Repair Disk, clear system cache files and only load Apple Software, extensions and fonts.

The loading will be slow - normal. This process may or may not allow the update process to complete - hopefully successfully
