Why doesn't IntelliJ IDEA open the Java project in WSL2?

Question

I'm using WSL2 + Windows 11 + IntelliJ IDEA Ultimate 2024.2.2 + Gateway 2024.2.1.

I have a Java project in WSL2, and when I try to open it using Gateway, its status shows as "running," but the project doesn't open in IntelliJ IDEA. Additionally, IDEA doesn't display any window.

However, when I open a Rust project in Gateway, it correctly opens in JetBrains RustRover.

Why doesn't IntelliJ IDEA open the Java project in WSL2?

I have deleted the folder

.cache/JetBrains/RemoteDev/dist/c37955a7f3f02_ideaIU-2024.2.2/
.cache/JetBrains/RemoteDev-IU/

then I tried to open the java project again, but when it finished downloading some dependencies and start the IDEA in WSL2, still nothing happens.

Here are some logs when I clicked to open the project.

idea.log in WSL2 .cache/JetBrains/IntelliJIdea2024.2/log/idea.log
