Welcome to the forum!.
Unfortunately your post remained unnoticed.
My answer is that yes, hopefully you can do something.
First I have a question: how long do you have that plant? If for weeks, the flowers could reach the end of their life span and now are dying.
But, it's probable that at least a part of the root system is gone. Pull out the plant carefully, check the roots, cut off what is bad (black, soft, mushy, hollow inside) using a sterile tool, and re pot. Good roots are firm, have green/white color.
If all the roots are dead than the problem is bigger.
