Answer 1

First of all, I recommend contacting the plugin developer.

java.lang.NoSuchMethodError: org.bukkit.inventory.Inventory.getTitle()Ljava/lang/String;

Here, here is your mistake - it was not possible to find the getTitle() method.
Here is what Google gives:
result
Here, another approximate error here - https://github.com/FabioZumbi12/RedProtect/issues/425
if he has a repository there) and contact the developer

Answer 2

This is a problem with the plugin, or there is some kind of conflict, maybe the kernel version is not suitable
