Touch stopped working after Android 9 was updated

Hi, I broke the display, bought a new one on aliexpress.
Installation succeeded. The display worked.
The phone asked for an update (Some version of Android 9, probably the penultimate before Android 10), which I did. After booting, but did not working touch screen ..
I did the factory settings, but that didn't help.
I didn't deal with the phone for some time, I thought that another system update would fix the bug.
Yesterday the phone got an update to Android 10, I installed it here, made the factory settings. But the touch screen still doesn't work. (I control the telephone via the OTG adapter)
I read how to do a downgrade, but by doing an update on Android 10, I about closed the option that is described here . https://forum.xda-developers.com/nokia-7-plus/how-to/finally-downgrade-phone-official-t3849437
I read a lot of discussions and came to the conclusion that I probably bought the wrong display.
Or is there a solution? Downgrade system? Upload another touch panel firmware?
Now this is on the phone Touch panel firmware version: 07 Goodix-V1.017.20.
I attach a photo display, it might help something.
Is there any way to identify my touch problem?
Thank you for any help
