I am working with VV/VH Sentinel 1 descending data in Google Earth Engine but there are large areas misisng as shown in the screenshot below. The image indicates the mean data from 1-31 August. The issue appears to have started around January 2022.

Sentinel-1B died in Dec. 2021. https://www.esa.int/Applications/Observing_the_Earth/Copernicus/Sentinel-1/Mission_ends_for_Copernicus_Sentinel-1B_satellite
The pattern in your image looks much like the planned acquisition strategy:
