Crash reporter does not give me a link to a trace.
Not using a debug build, so seems different to Bug 143640

"unique_ptr->optional in SwXTextPortion"

This is what I see on the console in a debug build:
/usr/include/c++/11/optional:446: constexpr const _Tp& std::_Optional_base_impl<_Tp, _Dp>::_M_get() const [with _Tp = com::sun::star::uno::Any; _Dp = std::_Optional_base<com::sun::star::uno::Any, false, false>]: Assertion 'this->_M_is_engaged()' failed.
