I have imported point from a csv file with the xyz coordinates in the attribute like this in QGIS.

enter image description here

And now I want to add Z value to the point. I try to use v.to.3d to add Z value but I get the error. How to fix this or Is there any tool to do like this?

Try using the "Set Z Value" tool instead -- it can be used to set geometry's z value as either a fixed value or from either a feature attribute or expression based value.
