Background of the issue:
My client runs the website in German. Then we added English with WPML. After a few months we added Polish as another language.
Symptoms:
Since adding Polish, the standard language for the shop seems to be Polish. It gets clearer in this video: hidden link
Questions:
How can I change the standard language for the shop back to German?
I've already tried to re-save the permalinks in Settings -> Permalinks, but unfortunately, it didn't help.
Please try the troubleshooting section.
1. Take a backup of the DB of your site.
2. Go to WPML -> Support -> Troubleshooting (link)
3. Once on the troubleshooting screen, press the following buttons and check if it helps. Press each button at a time and wait for the process to complete.

We suspect a collision with the theme or another plugin might cause this problem. If possible, get your site into a minimum environment, switching to a default WordPress theme like TwentyTwenty-Four and having no plugins activated except WPML.
First, you must check if the problem persists when just the theme is switched to TwentyTwenty-Four (for example). If it persists, deactivate all plugins except WPML and its add-ons and WooCommerce without any extensions. Then, please check if the problem persists. If it does not persist, start by activating the plugins individually and checking when the issue comes back, then report to me which plugin was the culprit.
**** Important! Please make a full site backup (files and DB) before you proceed with those steps****
*** If your site is live, you might want to try those procedures in a staging environment or a snapshot of your site on your local server or another server. ***
