[Warten auf die Bestätigung des Benutzers] Critical error on Toolset Archive pages after Elementor Pro update to 4.2.1

Hi Toolset team,

After updating our plugins, our Toolset Archive templates are throwing "There has been a critical error on this website" on the front-end. Single post templates load fine — it's specifically the Archive pages that are affected.

I isolated the cause by deactivating plugins one at a time: deactivating Elementor Pro resolves the issue and the archive loads normally. Reactivating it brings the error back immediately, so it appears to be a conflict between Toolset Blocks and Elementor Pro 4.2.1.

Setup details:
- Toolset Blocks (Views): 1.6.26
- Toolset Types: 3.6.2
- Elementor: 4.2.1
- Elementor Pro: 4.2.1
- WordPress: 7.0.2
- PHP: 8.1.34
- Theme: Astra 4.13.8
- Hosting: Pantheon

The affected archive templates use a Toolset View that outputs an Elementor template via shortcode (e.g. [elementor-template id="480405"]) in the Loop Output. The archive preview loads fine in the WP admin editor, but errors on the live front-end.

Could you take a look and let me know if this is a known compatibility issue with Elementor Pro 4.2.1, and whether there's a fix or workaround while we wait on an update?

Thanks so much,
