Difference between datas - GA4 vs GDS

I have a data difference between google data studio and GA4.

GA4 is connected to Google data studio, so the same results should come up.

However, on google data studio for the period January-November 2024 I have the same figures on GA4 and on Googlet data studio, which is fine, but that's not the case for the period January-November 2023, I don't have the same figures.

GA4 for /16-brise-vue-occultants page path for the period January-November 2024: 7874

GDS for /16-brise-vue-occultants page path for the period January-November 2024: 7874
