Unable to start pgAdmin on first install

I installed the latest version of pgAdmin on my Win11 laptop (where I've never installed pgAdmin before).

I rebooted per the final instruction.

I clicked the pgAdmin icon and got a splash screen. Then, after waiting around 2 minutes for the splash screen to complete whatever it was trying to complete, I got a message with the title "Fatal Error": The pgAdmin 4 server could not be contacted.

I tried clearing pg* from the Roaming folder per this: https://stackoverflow.com/questions/43211296/pgadmin4-postgresql-application-server-could-not-be-contacted?rq=1

No luck.

Since this is a fresh install, I'm not keen to keep debugging before moving on to some other tool which works upon install. I can get my data using python+psycopg2 already, pretty easily.

Any thoughts?

Here's the full output from that window:
