SteamlessTimes causing bootloping on Deck's with multiple Steam accounts

[TrainDoctor]

Here's the original issue filed to the Decky Loader page's issues.
This issue has multiple backend logs attached that can be referenced to help debug the issue.
I've also attached some system logs that include the CEF logs. These were grabbed on the latest pre-release of decky-loader: steamwebhelper.log.

@nabel0 was able to reproduce with a 100% reproduction rate using just decky-loader and SteamlessTimes on a Deck with multiple Steam accounts.

This is a significant issue that causes the deck to boot-loop the Steam client is forcibly set to Stable (redownloaded and installed in place of any beta/preview Steam clients). Information on whether this changes the deck over to Stable SteamOS as well has not been confirmed.
