ALVR client keeps losing connection after playing for a while

[mysticfall]

ALVR works fine on my Linux PC/Quest 3, except for one problem. After playing for a while (usually 15-20 mins), the client (installed with SideQuest) starts disconnecting and reconnecting indefinitely until I manually exit and restart the app.

It happens with games like Skyrim or IL-2, but not with Subnautica for some reason.

Could anyone suggest how I should debug this problem?

Thanks!
