Generally in Gimp 2.10 gradient tool, hitting the enter key or selecting another tool will fix it in place. Esc or closing the dialogue window cancels.
Might be that you clicked on some other window/dialogue and lost focus in the Gimp window.
Not sure what you are doing without your image but as a guess.
Shirt on top layer with layer mask. Made a feathered selection to constrain the gradient. Click in the layer mask to make it active. Start gradient tool. https://i.imgur.com/ZiTUcNB.jpg Note the layer mask shows no change until the gradient is fixed.
Hit enter to fix gradient. The layer mask now shows the result. https://i.imgur.com/PiyPZdV.jpg
With the selection off. https://i.imgur.com/prRcEwH.jpg
Is it something like that you want?
