Build error: Cannot read properties of null (reading 'lang')

[freedomlang]

After update to v15.11.0, i'm facing error: Cannot read properties of null (reading 'lang'). Everything is fine, if i downgrade to v15.10.2

I met this also.

if (script || scriptSetup) {
    const lang = script.lang || (scriptSetup && scriptSetup.lang)

script may be null.
