So just a recap of what happened between the European Commission and the European Parliament and why the regulation has expired (it's a long story, I'm probably missing many nuances):
- In 2021 the European Parliament voted in favor of a temporary regulation that allowed companies to (i.e. voluntarily) scan private communications. Let's call it Chat Control 1.0. They chose to enact this because US companies were already scanning private messages in violation of the ePrivacy Directive which had come into force in the previous year. Instead of enforcing this directive, they chose to (temporarily) legalize the scanning of private messages while preparing more permanent legislation.
- In 2024 Chat Control 1.0 was extended for another 2 years. An amendment was adopted that explicitly noted that after this time "[the regulation] shall lapse permanently".
- From 2022 to 2025 the European Commission (together with member states) has proposed mandatory scanning, later updated with a proposal for client-side scanning (defeating end to end encryption), AI classification of image and text content, age verification and a lot of other invasive measures. This is what is known as Chat Control 2.0. The European Parliament has again and again voted against this proposal.
- In 2025/2026 the European Commission finally (temporarily) backed down from Chat Control 2.0 and instead proposed to extend Chat Control 1.0 for another 2 years, but has completely failed to negotiate with parliament to adopt a text that explicitly puts fundamental rights up front, something that a majority of the European Parliament had asked for since 2021.
- In response to this, the Civil Liberties Committee of the European Parliament tabled amendments [1] that explicitly limits the regulation to the subject matter and prevents it from being used to weaken end-to-end encryption. Many of these amendments were adopted.
- Consequently, many conservative members of the European Parliament voted down the entire extension of the regulation. They apparently felt that it was better to let the regulation expire so that they gain more negotiation power to adopt a version of the regulation that the has less safeguards or contains measures like in Chat Control 2.0.

I think your recap is missing a pretty large step at the very beginning, which is that AFAIR, the EU Parliament put together this temporary regulation to a posteriori allow the scanning that was already being done, outside of the law, by those US companies on EU citizen messages ; and the temporary regulation was put in place until a proper framework could be agreed upon.
