Javascript error

Hi, before all thanks for all the work you’ve done !

I have a big issue who completely forbid me to get the “customize” page works anymore.

I’m running on shopkeeper 2.2.5 (latest) update from september 20 and latest wordpress / woocommerce

I got the error from this java asset “wp-color-picker-alpha.js”
the error is :

wp-color-picker-alpha.js?ver=1.2:27 Uncaught TypeError: Cannot set property 'toString' of undefined
    at wp-color-picker-alpha.js?ver=1.2:27
    at wp-color-picker-alpha.js?ver=1.2:390

I can’t acess to the style editing, all theme settings :'(

If there is no fix at this time, do you have a temporary hack for get access back to the cusotmizing panel pls ?

thanks in advance
