AirPods 3 won't reset

[ViMK3]

Hi all, I have a problem with my airpods 3.
After unpairing them from the iphone and holding down the button behind the case, it won't reset.
To be more specific I open the case and the LED is green, I keep the button on the back pressed until the LED changes from white to amber, but it keeps flashing amber and never turns white (reset complete).
It's not the first time this has happened to me and usually by repeating the procedure 3 times the airpods reset successfully, but this time I just can't reset them and it's not normal for me.
Someone has ever experienced something like this ?

the same is happening with my AirPods Max and I have read other websites that it happens on AirPods too.

I think it around November last year that it started.

After reading some of those posts I followed the advice to just leave the AirPods alone for a long time - and next time I tried they reconnected like they do the first time.

I’ve done this twice - first time I waited half a hour, second time was nearly two days but right now that fox isn’t doing anything.
