I think you have a problem when loading.
make sure you do well to follow the path of the plugin.

what?

Code:

main: Praxthisnovcht\CustomChat\CustomChat

Code:

src\Praxthisnovcht\CustomChat

it is wrong to withdraw to "Main"

PHP:

class SkyWars extends PluginBase implements Listener{

so what do I need to do

PHP:

class Main extends PluginBase implements Listener{ 

because the path you have drawn is this

PHP:

main: SkyWarsPETeam/Main

if I'm not mistaken just his

Same error

other error

Code:

SkywarsPe / src / SkyWarsPETeam / Main.php 

Code:

namespace SkyWars;

the path is

Code:

namespace SkyWarsPETeam;

I'll make PR soon. Where's the repo?
