I'm measuring the areas under curves from gel lane plots in Fiji (i.e. ImageJ 1.53t with Java 1.8.0_322) by drawing lines on the plots and then using the magic wand tool to select the area, which returns a value.

After doing many measurements (around 200, I think), it won't let me measure anymore, and returns a pop-up with the following exception when I try:

The only way I can resolve it so far is to re-plot, which is very disruptive to my workflow. For reference, I'm measuring 2D arrays of spots with hundreds of samples per blot, so having to re-plot several times really sucks!

I'm currently running Fiji/ImageJ on Fedora Linux 36 (Workstation Edition, 64-bit), but I've also had this problem on my old MacBook Pro. Why does ImageJ do this, and can I fix it?
