Accidentally deleted partition on SD card

“During the Windows reinstallation process, I have accidentally deleted the partition on my SanDisk micro SD card that is connected to my computer. In Windows Explorer, I still can view the drive icon but it says please insert a disk into removable disk (F:) when I try to open it. Does my SD card partition still exist? If it is, how can I recover the deleted partition on the SD card and access it again? I don’t want to lose the data saved on it. Any advice will be appreciated!”
