[clutcher]

@mgroth0 Thanks for reporting, looks like something related to 2023.3 changes in notifications on start up. Shouldn't affect regular functionality of plugin.

[clutcher]

Next version 2023.7.13(would be available on marketplace in 1-2 days) should fix that issue and be compatible with 2023.3 versions of IDE. Closing as for now.
