@maraf I found a very similar failure in 8.0. Is it the same root cause as the one initially reported in this issue? This one was reported for windows, while the one I just found happens in linux:

• Affected PR: [automated] Merge branch 'release/8.0-rc1' => 'release/8.0' #92374
• Queue: browser-wasm linux Release WasmBuildTests
• Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=413445&view=logs&j=1fa93050-f528-55d3-a351-f8bf9ce5adbf&t=a9f1a437-3b59-5900-1137-ec6cae9a530c
