I used RKDevTool_Release_v2.96-20221121, Rockchip_DriverAssitant_v5.1.1.
I didn't make any changes to the config.ini file, the RKDevTool started in English.
If you get an error saying the tool cannot find the config.ini file, move the whole folder somewhere else, e.g. to the C:\ root (it's some path issue, either special characters or the path is too long or something like that).
You know the touch screen is in the correct mode when the app says Found One LOADER Device; not Found One ADB Device or Found One MSC Device or No Devices Found.
You can just simply press & hold the recovery button on the device (IW: left-hand pinhole, TT: volume up button) while plugging the USB cable in, it should start in the correct LOADER mode immediately. (This helped me with a 10" IW which either wouldn't react to the Reset button or would always end up in the ADB mode for some reaseon.) Or plug the USB cable in first, then press & hold the recovery button and then just shortly press the Reset (pinhole) button if it's easier. The device should show up in RKDevTool almost immediately as a LOADER Device, it shouldn't be necessary to keep holding the recovery button for long.
