Flutter project not loading or or devices not found

[akshaybabloo]

In IntelliJ IDEA 2025.2, Flutter project is not loading. This started happening when I was first running the application in debug and there after it stopped loading the available devices or running the project. flutter doctor is working and I am able to run the application from CLI and VS Code. Screenshot below

Restarting the Flutter demon gives me below exception

And sometimes I get this error

I tried restarting the IDE but the issue still persists.

Looks like the issue was with Windows defender (not sure yet) but after restarting the system, it works fine. Will reopen it if the issue comes back.
