Fatal Error when exporting the WordPress theme

Hello everyone,

After updating to version 8.62, I receive a “Fatal Error” in the browser after exporting the WordPress theme file.

After investigation with the WordPress Debugger, it appears Block elements are causing this error. If I remove them, the error does not occur.

Can anyone confirm this issue?

p.s.: When I revert to version 8.5, the export works without errors.
