[MrBlasyMSK]

Apparently it is an error with MysteryCrate, if you remove the plugin it works correctly

I do not know if it can be fixed in any way, close the issue if you think necessary

@brokiem

[MrBlasyMSK]

It gives an error with the Mysterycrate particle option

showParticle: false

If you have this option like this, it works correctly

[MrBlasyMSK]

I rectify, I have been tested and it crashes within seconds of moving in another world

Error occur on this line https://github.com/ifera-mc/MysteryCrate/blob/master/src/JackMD/MysteryCrate/EventListener.php#L239
because the author didn't check the entity instanceof Player and the plugin is archived, please don't use that plugin
