Server keeps overloading to the point of a crash and I don't know why.

I have a private SMP and recently I've been experiencing issues with it. The server at random times overloads to the point it crashes. I've been trying almost everything to fix this but no success. This is why I decided to ask the Aternos community. Here is the list of plugins I have on the server:

DiscordSRV

OpenAudioMc

SkinsRestorer

I am also experiencing this same issue on another server that have these plugins:

CoreProtect

DiscordSRV

Essentials

LoginSecurity

PluginMetrics

SetHome

SimpleSpawn

SimpleTpa

SkinsRestorer

Vault

WorldEdit

And only these match up:

DiscordSRV
SkinsRestorer

And I've already ruled out both of these plugins. Here's the link to view the log, I'd like to get a response ASAP.

Tried doing it but didn't fix my issue. Here's the link to the log after I tired. Still looks like the error is related to same UUID but deleting the playerdata didn't work.
