Euphony Blocks Pro causes critical error after activation

Hello, I purchased Euphony Blocks Pro 2.2 and installed it on my website: https://shayanabyava.com The free Euphony Blocks theme works normally. I installed and activated Euphony Blocks Pro 2.2, and also installed FSE Pro as required. Both license keys are valid and activated successfully. However, as soon as I activate Euphony Blocks Pro, the frontend shows: "There has been a critical error on this website." If I switch back to the free Euphony Blocks theme, the website immediately works normally again. I also tested the site with FSE Pro deactivated, but the critical error remained, so the problem appears to be related to Euphony Blocks Pro itself. Environment: - WordPress 7.1 - Euphony Blocks Pro 2.2 - FSE Pro installed - Both licenses activated - Free Euphony Blocks works correctly Could you please check whether this is a known compatibility issue and advise what I should do before activating the Pro theme again? Thank you.
