I told you to send me the link through my discord. because that plugin is paid, if you send me the link here, someone can also download it.
And sorry, but I don't have that time to search in our conversations to look for the password. Make things simple. Next time follow my instructions and send me the link through discord. I manage to open the file and I can already see some things wrong:
Your plugin manager is full of warnings:

It's best if you keep that warning clear. Because RPG Maker only shopws to you one warning at time. If you keep disabling the plugins that are showing the warning, you will end up on this warning below:

So the plugin order is wrong.
But even so, that was not the problem. Because there is no problem at all. The plugin is working perfectly. You choose to use two bitmap fonts that are almost the same. When you change the fonts using the escape code and the plugin commands, they are changing, but it was(for me at least) almost impossible to identify the change because the two fonts are almost the same.
So, to confirm that the plugin is working, I changed the text color of the DWFont, just to make sure that the fonts are really changing with the plugin commands and escape codes:


After you changed it to the DWFont, you can open the menu and see the changes there too.
(I think it is not compatible with the MK UI Customizer plugin though. Because it is not changing the HP/TP fonts of the main menu when tha plugin is enabled)
