Ghost 'repeat key' // Mouse selection inhibit // Odd behavior

I executed a factory restore on this Macbook Air and installed Big Sur, later to execute another format and install Catalina due to program compatibility and plan to gift this to a friend who just started a business so they may use until it becomes necessary to purchase new.

ISSUES — The problems I am having are shown in the videos below.

• Ghost Repeat Key: https://youtu.be/xXPfdDMxor8
• Selection Inhibit: https://youtu.be/SRdhA9iZN_0

ATTEMPTED — These are processes I have attempted.

• No identified issues after a Self Diagnostic - https://support.apple.com/en-us/HT202731
• Reset PRAM
• Reset SMC
• Factory restore and clean OS install

Any information or suggestions appreciated as the Genius Bar is 2-3 weeks booked due to the current state of the world.

Stay safe all!
