language modes specified are incompatible

[kyrpav]

I am new to Esp32 with vscode. I have build a c++ initial program that works and i am trying to add some classes in different folder and files .hpp and .cpp.

In each of these files i get an error at the beginning of the file that:

command-line error: language modes specified are incompatibleC/C++(1027)

In hpp file i get it on class creation on first letter.
In cpp i get it on # of the include of the hpp file.

It is always the first char of the file.

I used F1 and select of language modes and for either .cpp and hpp files and for all cpp is selected and no selection works.

Is there any solution? I understand that disable squiggles is not the correct option cause they show also the errors.

Thanks
