message fail after installing recaptcha

Hey guys !

I have a problem with a form I just implemented. When you submit it, you should receive a mail with a file attached (our commercial presentation) and I should receive an other email with the message of people submitting.

Everything was working but when I activated Recaptchav3 it started considering everybody as a spam. So i deactivate the recaptcha but now my form doesn’t work anymore :/ It doesn’t consider me as a spam but just send me an “message fail” error. Then i try to deactivate every other plugin but no more luck and it’s still giving me an error each time I try to submit it. I also tried to create an other form, almost change every fields but still nothing. I’m running out of ideas. If someone can help, it would be lifesaving ^^
Thanks !
