Evny x360 15-ee0003nl pen, usb ports and touchscreen issue

Product: HP ENVY x360 15-ee0003nl bought 4/5 years ago. Using Windows 10 version 22h2 (the last one). I have a HP tilt pen 2.0 nearby the desk that is always connected via bluetooth to the laptop.

I was using my laptop normally (I think I was just using google chorme and had a bunch of tabs opened, nothing unusual), with a wired mouse which has always worked fine. Suddenly the mouse disconnected, with the windows sound for disconnected device, but the wire had nothing wrong. I tried physically removing and reconnecting it some times but it didn't work. I tried if the mouse was working with other laptops and it was fine. It seemed a USB port issue and I tried restarting the pc. When boot up, a message appeared saying the pen (which has always worked fine, for years) was not compatible with my laptop. So now the pen is not connecting anymore, even if I try to connect it again with bluetooth pairing (bluetooth works fine with other devices like wireless headphones).

The mouse now is still not working so I try using the touchscreen (I use it often even without the pen, even today, and it has never had any problem) and now it is not working too (luckily the trackpad was fine).

I tried connecting the mouse to the other USB 2 port (there are two 2.0 ports and one type C) and it was the same. I tried connecting other devices like an external hard drive and this one worked on the second port but not the first one, while other devices did the opposite.

I checked the device manager and I notice that the "HID compliant touch screen" (or something similar) was missing and there were two "HID i2c", one working fine but the other one not (it says Error 10). I tried checking for driver updates, in the device manager windows tab and the in the HP website with drivers. I didn't find anything for touchscreens or USB ports so I tried with downloading the BIOS and the bluetooth driver. After reboot I had to update my BIOS again but nothing changed.

At some point, after like 15 minutes, while the mouse was stille physically connected (but not working), I suddenly hear the windows notification sound for a new connected device and the mouse was now working again, even if i disconnect and reconnect it to the same port it works, but not in the second one. I was really confused at this point and after trying some other things (disabling and disinstalling the devices from the Device manager and rebooting, and re installing the drivers) I gave up and continued using the laptop normally but with no touchscreen and no pen, until an hour later when the mouse disconnected again. This time I managed to get it to work almost immediately but after some time (40 to 50 minutes) it stopped working again, and I haven't managed to fix it since.

I will contact support when it opens but for now I ask here. Thank you.

I forgot to say that I already tried using the HP diagnostic software and running all the tests but it didn't find anything. I don't think it run any test for the touchscreen, maybe it is not recognizing the touchscreen at all.
