Connection error (PC is online.)

I downloaded the trial version and tried to open the app.
I got a connection error message even though I am online.

What should I do?

mac os 12.3.1

What version exactly?
What does it say in finder?

For some reason, I was able to open the software successfully this morning.

However, a new problem is that when I try to open extensions such as SketchUp Extension Warehouse
「The SketchUp Extension Warehouse requires an Internet connection. Please connect and try again.(original text:SketchUp Extension Warehouseにはインターネット接続が必要です。接続してからもう一度お試しください。)」and cannot open it.

The same is online.

mac os :12.3.1
SketchUp Pro : 22.0.353
