Chrome OS customers have claimed that the latest system upgrade contains a serious problem that locks them out of their Chromebooks. When users attempt to log in after installing version update 91.0.4462.165, Chrome OS fails to recognise their Google account passwords for some reason. Other major issues, such as boot loops, could be caused by the failed upgrade.
Update 91.0.4462.165 looks to be no longer available, according to 9to5Google, and Google is working on a patch to remedy the faults it created, which should be available soon. To avoid these problems, don’t download or install any new Chrome OS upgrades until Google’s new patches have been thoroughly tested.
Even still, it’s preferable to using your Chromebook as a paperweight while Google tries to resolve the current round of Chrome OS flaws. However, you can conduct a factory reset on your Chromebook right now to regain full access to your Google account. This clears off all of your saved files and programmes, as well as your Google accounts and restores your device’s default settings. If you absolutely must restore Google account access on your Chromebook straight away, we do not recommend a factory reset.
