Audio Engine probleme

[Maxidingue]

Hi all Protools Users,

I am running Protools 2018-4 on my iMac core i5 3.3 MHz with 24 Mo RAM
My OS is Mac OSX High Sierra
My "sound card" is a Behringer X32 Rack
I also own an S3 station
Until now everything was OK but yesterday when i tried to load the last projet i made, i have a strange message stating that "Protools was unable to find the sample rate frequency on the mentionned value" (or something like that. I am french and tried to translate.
Reinstall Protools but always the same message

My Behringer X32 work fine with Ableton Live and all my gear hook to it

Any help

Thans a lot
