Your screenshot shows that the Gaomon tablet settings have been allocated to ‘All Programs’ as a general profile.
You should create a specific profile for krita, close/reopen the tablet utility, then select that profile and make sure the settings are correct for it.
Are you sure that the Wintab vs Windows Ink choice has been setup at both sides, i.e. in the krita settings and in the tablet settings?
Also, to be sure, after changing any settings in the tablet or in krita, close the tablet utility and also restart krita.
Edit:Add: And another thing… Have you checked on the Gaomon website to make sure that you have the latest driver update installed?
If not, please do that.
Remember to fully uninstall the old driver, restart your computer, install the new driver (following the procedure instructions in the manual), then restart your computer and open the tablet utility and go through all of the advice again.
This is what it’s like setting up tablets and getting them working.
