syntax error on pgAdmin4 start

Hi, this is my first message here.Today my pgAdmin4 console doesn't start anymore... it takes lots of time and then a pop up appears complaining that pgAdmin server could not be contacted

the log is the following and it ends with this error:
 File "/usr/lib/python3.8/site-packages/pgadmin4-web/pgadmin/browser/server_groups/servers/databases/schemas/tables/row_security_policies/tests/__init__.py", line 1
    SELECT rel.oid, rel.relname AS name,
           ^
SyntaxError: invalid syntax

My system is Linux OpenSuse Tumbleweed and the pgAdmin version is 4.26-2.1 (the latest available for my system)
Recently I got some updates for python subsystem... may be this be the source of the problem?
How can I fix it?

thanks in advance for any hint
Marco
