lupdate doesn't update my .ts files anymore

After upgrading Qt VS Tools to version 2.9.1 (rev.6), the lupdate command doesn't update my .ts files anymore.
I try to add a new widget in my .ui then I run the lupdate command to add new translations to the .ts files.

With version 2.7.2 => .ts file is well updated containing the new translation
With version 2.9.1 => .ts file is not updated

I raised the log level to diagnostic and I collected the attached logs.
