resolveComponent not working as expected

const formatBlockName = (): string => {
    const type = props.data.blockType as string;
    const typeFormatted = type.slice(0, 1).toUpperCase() + type.slice(1);
    return `Block${typeFormatted}`;
};

const blockName = formatBlockName();

const Block = resolveComponent(blockName);
const Block2 = resolveComponent('BlockContentSection');

<component :is="Block" :data />
<component :is="Block2" :data />
