Apple pencil 2 doesn't work after iPad update

After upgrading to IOS 13.6.1 on my iPad pro 11" serial number DM***D8K, my apple pencil 2 doesn't work anymore, doesn't appear in the devices, the battery status doesn't pop out, nothing, now it is just a useless tool, which i really need for my job.

I already tried all the suggestions to try to fix it, that you can find on the web.

It is since this morning that i've been working on it, still not working at the moment, totally dead.

Thanks for any advice and suggestions for a solution
