I am facing with problems with VHDL with EDA playground - Any solutions are welcomed.

design.vhd

library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;
use ieee.std_logic_arith.all;

entity SwitchEncoder_vhdl is
 port( clk                    : in std_logic;

     key_out                : out std_logic_vector(3 downto 0));
end SwitchEncoder_vhdl;

architecture SwitchEncoder of SwitchEncoder_vhdl is
 begin  
process(clk, key)
begin
 if rising_edge(clk) then 
  case key(15 downto 0) is
   when “0000000000000001” => key_out <= “0000”;

You're using the angled quote characters, isntead of the simple ones.

“0000000000000001” should be "0000000000000001"
