Editor Crashes on Startup #15871

Open AMZN-alexpete opened 1 year ago

AMZN-alexpete commented 1 year ago

Describe the bug After creating a new project with 23.05 and starting the Editor.exe it crashes. Happened several times before in stabilization/2305 branch, but wasn't able to reproduce it after all assets were compiled.

Possibly relevant: LY_RENDERDOC_ENABLED andLY_PIX_ENABLED were set to ON when configuring AutomatedTesting in the stabiliztion/2305 branch, however the issue is reproducing in the installer build that doesn't have those flags.

It looks like Editor crashes in CStartupLogoDialog::SetInfoText when it calls m_ui->m_TransparentText->setText(text); from a thread other than the main thread. When I was attempting to fix this, moving the call to the main thread seemed to fix the issue, but then after all the assets were processed the issue did not repro.

Thread: APConnectRecv
