Lemmy keeps signing me out of lemmy.ml

For the past several hours the Lemmy website has been signing me out. When I close a tab signed into lemmy.ml and open a new tab later, I get the unsigned home page and I have to sign back into the website.

I'm using Lemmy 0.18.0 and I have an account at lemmy.ml. I'm using chromeOS Stable 114.0.5735.205. While I haven't changed my desktop setup for at least the past several weeks, the only thing that rings a bell is yesterday I got the chromeOS 114.0.5735.205 update.

The issue also occurs with Chrome 114.0.5735.147 for Android on my Pixel 7 Pro and the Lemmy PWA.

Updates

1. I also noticed the Lemmy user interface is now in Italian (I'm in Italy) despite having set it to English.
2. The user interface language is back to English.
