You are trying to write to the file (while you have open it for reading).
Use fread (or fscanf) for reading, see fread[^].

Make use of fread / fgets using your file pointer of your file.

A sample of fgets is as below.

FILE *fp_r = NULL;
	char buff[2049] = {""};
	
	fp_r = fopen(file_path, "r");
	if(fp_r)
	{
		while(!feof(fp_r))
		{
			memset(buff,0,sizeof(lv_buff));
			fgets(buff,2048,fp_r); // Read your file data
			
			// do something with your buffer read
			....
			...
			..
			.
		}
		
		fclose(fp_r);
	}
	else
	{
		// return file open error
	}
