Scrolling with up down arrow keys disables keyboard intermittently. HP laptop, Firefox 125.0.2 Win 11 pro

When browsing with Firefox, scrolling with the up/down arrow keys intermittently causes the keyboard to be disabled. Trackpad and touchscreen still function, but keyboard becomes completely disabled, requiring a reboot.

This ONLY happens while browsing with Firefox browser. I cannot deliberately reproduce this, but it happens frequently - up to several times a day. It seems to be tied to multiple key hits on the down and/or up keys. This only happens in Firefox, not in any other apps, including Visual Studio.

This is a brand new HP laptop. HP support says that this is a Firefox support issue because it only happens on Firefox and no other programs or scenarios.

Can you please help me to identify, troubleshoot and resolve this issue? I am a software/database engineer but this is a little outside the scope of my knowledge. I should be able to conduct any tests or provide any needed feedback at a useful level with only a reasonable level of hand holding. I suspect that Firefox is somehow inhibiting or disrupting the keyboard driver.

Does it still happen in Troubleshoot Mode?
