USB tethering doesn't work proberly

I recently installed LineageOS on my s3 and am currently trying to use it in tethering mode because my PC doesn't have a WLAN card but for some reason it doesn't work. It connects but is saying "no connection" and when i disable tethering i can use the WLAN on the phone perfectly fine.
Do you guys have an idea to fix this? would be much appreciated

Question Hotspot connects but no internet after android 12

I have updated to S2RKS32.92-11-21-12 rom via the Lenovo RSA (rescue & smart assistant app) as the OTA was not working (I have unlocked bootloader).
This was reported to be the latest rom (android 12)
Everything seems fine but when I turn hotspot on the other devices connect but cannot get any internet. It was working with the same devices when on android 11.
Any help welcome.
I tried a few things.
Firsrt of all, besides wifi hotspot not working, I also had no usb tethering or bluetooth tethering. So, no way to share my mobile data connection.
I tried another android 12 release (KYOTO_RETAIL_12_S2RKS32.92-11-30-8_subsidy-DEFAULT_regulatory-DEFAULT_CFC)
It did't fix anything.
So, I went back to the latest android 11 release I could find: KYOTO_RETAIL_11_RRKS31.Q3-19-98-4_subsidy-DEFAULT_regulatory-DEFAULT_CFC
This is working as before.
The other roms I found from https://mirrors.lolinet.com/firmware/motorola/kyoto/official/RETAIL/
and I followed this procedure to flash:
So. Does anyone have android 12 with working usb/bluetooth tethering and hotspot? If so, which rom to use?
