java error IOException: Mark invalid

[tralfalmadaan]

Hi,
For my cellpose segmentation, I wanted to try out the labelsToRois plugin, but it doesn't want to start, raising a java exception.

  Warning AbstractCLIJ2Plugin.setCLIJ is deprecated. Use setCLIJ2 instead.

I'm running 
Fiji (IJ 1.52t Java 1.8.0_172 64-bit) on Windows 11
I copied Labels_To_Rois.py to my plugin folder.

This is not a CLIJ vs CLIJ2 error is it?

Thanks!
