[Bug] Enabling NKRO on K3 Max causes random duplicated key presses in 2.4GHz mode

[hlysine]

Describe the Bug

Enabling NKRO via Fn+N on the K3 Max causes keys presses to be randomly duplicated even though no typos are made. The amount of duplications seems to correlate with typing speed.

This does not happen if the keyboard is connected via cable or if NKRO is disabled. The keyboard still correctly detects 20+ simultaneous key presses in 2.4GHz+NKRO despite this bug.

Example text:

The quick brown fox jumps over the lazy dog.

With 2.4GHz+NKRO (multiple tries at ~100WPM):

The  quick b rown fox jumps over the lazy dog.
The q uicckc brown fox jumps over  the lazyz dodg.
The  quickc brown fox jumps o ver the lazy dogg.
The quick browon fox j umps o ver the lazy dog.
The  quick broowon fox jumps over the lazy dog.

With 2.4GHz+NKRO (multiple tries at ~30WPM):

The quick brown fox jumps over the lazy dog.
The q uick brown fox jumps over the laz ydogg.
The quick brown fox jumps over the lazy dog.
The quick brown fox jumps over the laz ydog.
