Dynamic plugin requires restart on Windows

Hi there!!

I created a dynamic plugin, and deletion/updates indeed work without IDE restarts on MacOS (and I assume Linux, but I don't have a machine to test my plugin on this OS yet).

But there is an issue on Windows. I released an update for my plugin, and when I clicked on update, a popup asking me for restart was displayed.

I checked idea.log and I found the following entry. Keep in mind that I intentionally hid my plugin name and the absolute path (thanks for understanding):

I assume this is not an issue with my plugin since, as I mentioned above, it works well on MacOS (and presumably Linux as well). I suspect this might be an IDE issue, or a Windows issue (maybe Windows Security/Defender).

My IntelliJ version is the latest at this moment (2024.2.4).
The Windows version is 11 Pro 24H2.

I would appreciate any help/hint on this.

Thanks!!

Best regards,
Nahuel
