Seeking Free Photo Recovery Software for RAW Flash Drives

I recently encountered a frustrating situation with my flash drive, which turned out to be corrupted and now appears as a RAW file system. I initially used Disk Drill for recovery, and while I was making progress, I reached a point where the Software prompted me to pay for the full version to continue. Unfortunately, I’m not in a position to spend money right now.

I’m reaching out to the community for recommendations on reliable and, most importantly, free Software that can assist in recovering my precious photos from this RAW flash drive. The images are vital to me, so any suggestions would be greatly appreciated. Thank you in advance for your help!
