USB only charges when connected to PC. File transfer not available until restart

Zenfone 8 I006D

Sometimes file transfer doesn't work when connecting to my PC.  No options for selecting file transfer show up. The phone only charges.  It's not the PC or cable as several have been tried.  The issue goes away after restarting the phone, but this is inconvenient to do whenever I want to transfer files after the phone has been on for a while.
