Sentinel-1 no products found

I’m interested in doing flood mapping for a specific region, using SAR images from before and after the event. However, Sentinel-1 images are missing for this region (no products for more than 8+ months). I’ve done some digging and found out that Sentinel 1B was malfunctioning around the same time. Then it was sadly retired. During this same period there are also no S-1A images.

Where can I find a similar free source of SAR images? spanning July-August of 2022?
