I think this is indeed a dupe of Bug 1831236 and not something Mn/Wd specific because I've started to see more and more mochitests, like [this](https://treeherder.mozilla.org/jobs?repo=autoland&selectedTaskRun=Sev6OqamRAi0eU97xvcsKQ.0&resultStatus=pending%2Crunning%2Csuccess%2Ctestfailed%2Cbusted%2Cexception%2Crunnable&fromchange=0e9cb62ee3805ddb89441d8ba79a60974941a78c&searchStr=windows%2C11%2Cx64%2C22h2%2Cwebrender%2Cdebug%2Cmochitests%2Ctest-windows11-64-2009-qr%2Fdebug-mochitest-plain%2C5&group_state=expanded&tochange=7cad7000bc1c51f14ca241ac2aa08ac299612b8c) that have the same crash. Probably something triggered a spike in the failure rate for this crash. If you think the same way, please close this bug.
