NPE when plugin is disabled because Geyser or Floodgate are not present

When loading the plugin on velocity I encounter this problem

09:25:34] [Velocity Async Event Executor - #0/ERROR] [geyserpreventserverswitch]: Floodgate or Geyser not found! Disabling... [09:25:34] [Velocity Async Event Executor - #0/ERROR] [com.velocitypowered.proxy.event.VelocityEventManager]: Couldn't pass ProxyInitializeEvent to geyserpreventserverswitch java.lang.NullPointerException: Cannot invoke "com.github.camotoy.geyserpreventserverswitch.common.DataHandler.disable()" because "this.dataHandler" is null at com.github.camotoy.geyserpreventserverswitch.velocity.VelocityPreventServerSwitch.shutdown(VelocityPreventServerSwitch.java:63) ~[?:?] at com.github.camotoy.geyserpreventserverswitch.velocity.VelocityPreventServerSwitch.onProxyInitialize(VelocityPreventServerSwitch.java:47) ~[?:?] at com.github.camotoy.geyserpreventserverswitch.velocity.Lmbda$1.execute(Unknown Source) ~[?:?] at com.velocitypowered.proxy.event.UntargetedEventHandler$VoidHandler.lambda$buildHandler$0(UntargetedEventHandler.java:56) ~[velocity-3.2.0.jar:3.2.0-SNAPSHOT (git-7f776abf-b252)] at com.velocitypowered.proxy.event.VelocityEventManager.fire(VelocityEventManager.java:598) ~[velocity-3.2.0.jar:3.2.0-SNAPSHOT (git-7f776abf-b252)] at com.velocitypowered.proxy.event.VelocityEventManager.lambda$fire$5(VelocityEventManager.java:479) ~[velocity-3.2.0.jar:3.2.0-SNAPSHOT (git-7f776abf-b252)] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) ~[?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) ~[?:?] at java.lang.Thread.run(Thread.java:833) [?:?]

I use java 17 and my velocity version is the latest also the plugin version is 1.4

The error message itself could be improved, but the actual issue is

Floodgate or Geyser not found!
