After some of trial and error i stumbled across a solution that worked for me, by looking at the difference between a pure blueprint .uproject file and one that is associated with c++ files.
Posting it here in case someone else needs this.

After deleting the Binaries folder, Source folder and .vs folder, open the .uproject file with notepad ( i used NotePad++ ) and remove the “Modules” section.

I went from this:

    {
    	"FileVersion": 3,
    	"EngineAssociation": "4.23",
    	"Category": "",
    	"Description": "",
    	"Enterprise": true,
    	"Modules": [
    		{
    			"Name": "xxxxxxxxxxx",
    			"Type": "Runtime",
    			"LoadingPhase": "Default"
    		}
    	],
    	"Plugins": [
    		{
    			"Name": "xxxxxxxxxxx",
    			"Enabled": true,
    			"MarketplaceURL": "com.epicgames.launcher://ue/marketplace/content/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    		}
    	]
    }

to this:

    {
    	"FileVersion": 3,
    	"EngineAssociation": "4.23",
    	"Category": "",
    	"Description": "",
    	"Enterprise": true,
    	"Plugins": [
    		{
    			"Name": "xxxxxxxxxxx",
    			"Enabled": true,
    			"MarketplaceURL": "com.epicgames.launcher://ue/marketplace/content/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    		}
    	]
    }

The uproject file after this loaded up without any problems, and the c++ compile button is gone.
