Version 1.28.0 not working.

Describe the bug
After update to version 1.28.0 and restart I received an IDE internal error with the stacktrace below:

To Reproduce
Code or Steps to reproduce the behavior:

1. Update the plugin from 1.27.0 to 1.28.0
2. Restart pycharm ide
3. It will open a IDE internal error window with the stack trace.

Expected behavior
Install the plugin, restart the IDE without any popup error.

Screenshots
Screenshots of the error:

Additional context

• Plugin Version - 1.28.0
• PyCharm Version (or IDE version) - PyCharm 2022.3.3 (Professional Edition) Build #PY-223.8836.43, built on March 10, 2023
• Python Version - 3.10.10

A new information. I cannot rollback to 1.27.0 version.
After uninstall the last version, install 1.27.0 and restart the IDE, I got another popup error with the following stacktrace:

I've been getting the same issue for a long time. It's particularly annoying because the error icon in the IDE blinks red and when I check it's always this same error and it happens continually throughout the coding session. Do note that the plugin is still working as intended, just this exception needs to be addressed.

@tonybaloney could we please get a fix for this? :)

[tonybaloney]

Have you got access to the latest PyCharm version? This error means the version of the logging module used is not compatible with the one in the JDK, which is specific to the PyCharm version.

The PyCharm plugin APIs change frequently, so I can't continue to maintain backward compatibility between releases

[quantumpacket]

I'm using the following according to the About menu. The PyCharm version is the latest.

PyCharm 2023.1.4 (Professional Edition)

Runtime version: 17.0.7+10-b829.16 amd64

Thanks. The error you’re reporting is unrelated to the one in the OP comment. I’m looking into it

Oh, they appeared to be the same at first glance. Here is my stacktrace if it helps.

Sorry I was getting confused with the other stack trace

java.lang.NullPointerException: Cannot invoke "com.intellij.notification.NotificationGroup.createNotification(String, String, com.intellij.notification.NotificationType)" because "security.packaging.PyPackageSecurityScan.NOTIFICATION_GROUP" is null

This one needs a separate fix.

Your trace looks similar in that it's a loader bug and there's a version conflict between the logging module that PyCharm has and the one installed by this plugin as a dependency.
