White screen at launching issue (on CrazyGames)

[gritty nacelle]

We believe this is what happens:

• the games start downloading normally
• the splash screen (which comes from FILENAME.data.br) loads correctly
• in the meantime, FILENAME.wasm.br should initialize but fails to do so (there were no console messages of “out of memory” or “could not allocate memory”)
• the WebAssembly has been downloaded correctly, because otherwise the game would not have gotten to the developer’s splash screen (would have stayed on the Unity loader screen) and the files download would have not gotten all the way to the streaming assets (on a side note, blocking the download of settings.json, catalog.bin and the streaming assets does not prevent the game from working)
• throttling the download speed didn’t cause any issue
• our best guess is that Unity failed to fully initialize/instantiate the WebAssembly, and since Raf’s screen went black it could be that it initialized correctly and failed after that (but I don’t know why).

context loss during a build is usually due to hardware malfunction/limitation. does this happen on other devices? what specs does this user have?

[gritty nacelle]

-This specific user is on a (new) Mac, on Chrome 131
-also when logged out
-across our domains
-clearing indexededb didn't fix it
-also get it in Safari, but not in Firefox
-it happens right when the message about StreamingAssets appears:
[UnityCache] 'https://files.crazygames.com/crossection/16/StreamingAssets/aa/WebGL/audioassets_assets_all_d8fa90d652081f806c1593c10bd384f3.bundle' successfully revalidated and served from the browser cache

Any idea where these are coming from? Do they always precede the lost context log?

[gritty nacelle]

We tested again, reproduced the problem on the same game, this time without these warnings.

Here's the full console log of the user.

Any thoughts here @vagrant citrus @sullen adder ?

what are the other thousand warnings from in this photo? is it the same thing?

Our CEO just pulled a complete log export when he was getting the issue on https://www.crazygames.com/game/crossection . There are often ads related warnings; I reckon only the last 100ish lines are relevant in giving potential clues on what's going on. Please also note my earlier comment as this is what a dev on our side who has spent already a few hours on this has found.

Do you think you can help, or is there another channel we can try for this issue?
