Strange benhavior of pgAdmin 9.8 on Windows

Team:

I installed pgAdmin 9.8 on Windows 10 to teach a class. the query tool,
etc. seem to work well, but plsql tool shows a strange message, and
commands like \d seem to hang

Microsoft Windows [Version 10.0.22000.2538]

C:\Program Files\PostgreSQL\18\pgAdmin 4\runtime>"C:\Program

Admin 4\runtime\psql.exe" "host=localhost port=5432 dbname=dlh3
user=postgres sslmo
de=prefer connect_timeout=10" 2>>&1
psql (18.0)
WARNING: Console code page (437) differs from Windows code page (1252)
8-bit characters might not work correctly. See psql reference
page "Notes for Windows users" for details.
Type "help" for help.

When I type '\d', only the '\' shows until I hit return, but execution only
starts after I hit return for the second time.

Standard plsql works fine.

For the purpose of teaching novices pgAdmin/Postgresql 18 it would be nice
if I could use plsql in the context of pgAdmin - which used to work.

Thanks for thelp, Marc
