Getting stuck in ZwWaitForSingleObject

Post by UCyborg » 2025-09-24, 20:21

64-bit SSE2 version, currently 33.8.1.2 on Win11 23H2; I've been noticing this for a while with multiple versions, happens occasionally, but I only notice it specifically after logging off Google account and some time during Google's tab loading, after switching away to another tab, browser may get stuck, UI is unresponsive, but not considered unresponsive by Windows, you can minimize the window, resize it, the content resizes, or even close it, just can't click anything in the window. Media content in the window on other tabs keep playing normally, at least the audio. If you close the window, browser process doesn't end, RAM usage stays the same at the moment of closure.

I noticed one of the threads just waits forever on something.

Does it say anything?

It also keeps spamming through OutputDebugString: "[JavaScript Error: "https://www.youtube.com/watch?v=somevideoid : Unable to run script because scripts are blocked internally."]"
