Hello @WhyEden and welcome to the TeamSpeak Forum.
If you have a Plugin installed ( I assume that the Client is crashing 99% due to the plugin), then please try start parameter -safemode. This will disable plugins and the client may be usable again. Now you can remove 3rd party plugins and maybe the client won’t crash when you remove the parameter again.
On Windows make a right-click on the shortcut you usually would use to start the client and then select properties. Then add the parameter as shown.
If it’s the Plugin that Crash the Client, then the plugin you are using is probably no longer up to date and needs to be updated by the plugin author
Otherwise can you please post your full TeamSpeak 3 Client log please.
You will find the Client Log under the following Path: C:\Users\your_Username\AppData\Roaming\TS3Client\logs
