Running flutter app in emulator freezes windows

Steps to Reproduce

1. Create a sample flutter project in the IDE.

2. Create a virtual device in AVD Manager

3. Run the app on the emulator. Windows Just freezes. Only option left to restart the system using the power button.

4. Just starting the emulator in the AVD Manager takes up lot of time. Below issues are recorded in the event log with running the app. `7:30 PM Emulator: glTexImage2D: got err pre 😦 0x502 internal 0x1908 format 0x1908 type 0x1401

Having the same issue. Where do I find the log files?

Got it sorted out. I deleted the /.dart_tool, /.idea and /build (everything inside) folders from my project directory and everything started working again.
