Your issue seems very similar to several variants within this Discussion thread, begun (and OP resolved) last December:
#298.
There were several subsequent resurrections along the same lines since then, the most recent of them raised only 2 weeks ago.
It'd be worth taking a look at the various earlier solutions throughout that thread to see if any might resolve your own instance of it. Failing that, yours and the most recent post in that thread may have identified a fresh variation.

I got this too on my 3b+ after installing onto an SSD, running off the SD card it worked just fine, so I assumed there was some issue with the virtual Python environment when run off the SSD, I'm just leaving it on the SD card for now.

Seeing a lot of reports of errors of this nature. It's starting to look like the latest chromedriver (or related package) broke stuff.

Curious: does it work in headless mode? ./pikaraoke.sh --headless note that you'll have to manually open a browser and go to the splash screen separately

I believe Selenium broke this. This ticket coincides when we started seeing this issue (2 weeks ago)
SeleniumHQ/selenium#14184

I don't have my pi handy, but might be worth trying reverting to the previous version of selenium:

Edit:requirements.txt
Change selenium to selenium==4.21.0
Re-run ./setup.sh

[jsalzer]

I was having the same issue and can confirm that changing from "selenium" to "selenium==4.21.0" fixed the websockets issue for me.

[vicwomg]

Thanks for confirmation.

I have committed the selenium version designation to the main branch. A git pull and rerun of ./setup.sh should fix this for affected users and new users should be fine.
