Inputs become broken after mapping more than 3 axi of a single gamepad stick

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

when mapping a controller all buttons work fine untill i map the sticks. i can map 3 axi of a single stick just fine, but after mapping all 4 axi of a single stick all input stop working from both controller and keyboard.

after deleting retroarch.cfg and restarting everything works fine and i can map everything and it works, but as soon as i restart retroarch again it stops working.

i have tried with 3 different controller with usb, 2,4ghz or bluetooth. all have the same problem

i have also tried all 4 input drivers.

on udev i can map 3 axi of a single stick before it breaks
on linuxraw it doesnt detect any gamepad at all
on paraport it doesnt detect any gamepad at all
on sdl2 i can map 2 axi of a single stick before it breaks

only happens on arch linux based distros

Expected behavior

mapping all inputs should work fine without anything breaking

Actual behavior

when mapping more than 3 axi of a single gamepad stick all inputs from keyboard and gamepad stop working

Steps to reproduce the bug

1. delete retroarch.cfg
2. start retroarch
3. map gamepad buttons and sticks
4. everything works
5. restart retroarch
6. all inputs stop working

Bisect Results

i think it started happening since version 1.16.

Version/Commit

You can find this information under Information/System Information

• RetroArch: 1.16.0.3 (arch linux package from extra repo)

Environment information

• OS: Endeavour OS with linux-zen 6.6.3 kernel

Reproduce the failure using the stated mapping steps on Arch Linux, comparing the input drivers and the saved retroarch.cfg behavior. Trace the input-mapping and configuration path from the point where four axes are saved, then verify that keyboard and gamepad input still work after restarting RetroArch.
