Since the topic is locked I'll comment here, I checked and it looks like the zip for grocy 4.2.0 contains packages/composer/autoload_real.php that has a modified date that is older than the one installed, which causes it to not be replaced (which does make sense)
My solution (Assuming the app is grocy and not grocy__2 and so on):

• Download https://github.com/grocy/grocy/releases/download/v4.2.0/grocy_4.2.0.zip to /tmp
• Make a full backup of /var/www/grocy
• Run su - -s /bin/bash grocy
• Unzip /var/www/grocy_4.2.0.zip and select it to replace all
• Remove the unzipped data directory rm -r data/
• Restore the data directory from the backup cp -a data/ /var/www/grocy/data/

This saved my installation
