Reloading Plugins causes 3.4 to crash?

Hi all,

I have 2 stores running 3.4. One, all of the plugins are fine and I don;t have an issue. The other, however, fails to load any plugins and when I try to reload them, it crashes my store. Any ideas as to why this is happening?

Thanks,
Jon

Check the System > Log.  Post related error messages here.

These are the errors that occurred. There are a number of warnings but nothing related to plugins:

Click View button next to one of those, and post entire stack trace here.

Do you have custom plugins?

I do have a custom plug in but it is in both of the store.

Here is the error text:
