Preonic:rev3 stops working after trying to wake the computer

After flashing the newest compilation of the firmware for preonic:rev3, the keyboard will cease to work if:

1. the mac goes idle / lockscreen
2. the user attempts to wake the computer with the keyboard.
   Reconnecting it solves the issue, until the next idle time.

Possibly related to this ticket: #6369

System Information

• Keyboard: Preonic
• Revision (if applicable): 3
• Operating system: MacOS 11.4
• AVR GCC version: Homebrew AVR GCC 8.4.0_2
• ARM GCC version: 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]
• QMK Firmware version: 0.13.19
• Any keyboard related software installed? None.

Additional Context

Keyboard bought from Drop around February/2021.
Used the stock firmware until now, keyboard used to work flawlessly under it.

Other issues that I've noticed, but minor:

• The keyboard no longer makes a sound when plugging in. (Related to this, I believe: [Bug] Preonic rev3 lights and chime not working with newly compiled firmware #13178)
• Music mode seems to be a whole pitch higher, with the 2 top rows being indiscernible. (Too high pitched)

Sample of the compiled binary:
preonic_rev3_default.bin.zip (July 14th 2021)

Command used for compilation and flashing:
qmk compile -kb preonic/rev3 -km default:dfu-util
