MS Forms Pro trial issue when transfered to Dynamics 365

Hello,
I have created a survey via Forms Pro (via trial version) but I can no longer consult it in Forms; it now only opens in Dynamics 365 Customer Voice and I can't retrieve the full content of each answer.
A "red danger" logo and a "form analysed" logo appear on the icon of the form in question:

How to retrieve the answers to this Forms Pro in Forms (without pro version)?
