Yesterday in the evening I received definition update ver. 230228-2. With that update IntelliJ could load properly, but my wired LAN connection became undefined, so I was unable to connect to Internet and to my LAN. I wrote about my problem to support team.
This morning, after definition update to ver. 230228-4, my wired connection seems to work properly and IntelliJ IDEA also loads without problems.
Thanks to support team!
