mh, habe einmal die PHP version von 7.4 auf 7.3 heruntergestzt: kein unterschied.

soll denn eigentlich hier \ScriptHandler::initializeApplication passieren?

Script Contao\ManagerBundle\Composer\ScriptHandler::initializeApplication handling the post-update-cmd event terminated with an exception

denn bis dahin läuft ja immer alles durch.

[herr rilke]

So.
Alles nochmal neu aufgesetzt. jetzt läufts.

[herr rilke]

... ggrrr - aber nur, bis ich ein

composer update

mache.

ist auch egal, ob PHP 7.3 oder 7.4.

wenn ich eine frische installation - alles läuft wunderbar durch - direkt danach mit

composer update

aufrufe, komme ich direkt wieder zum fehler:
