Error when changing point cloud and label directories in segmentation mode

[brufe163]

Describe the bug
When I'm trying to use my custom dataset (.pcd files) for segmentation, if I change the directory of the pointclouds and labels, the following error is displayed:

Loading segmentation labels from labels/segmentation/000.bin.
Traceback (most recent call last):

ValueError: The segmentation label doesn't match with the point cloud, label file contains {labels.shape[0]} while point cloud contains {num_points}.
Aborted (core dumped)

To Reproduce
Steps to reproduce the behavior:

1. Run labelCloud on the terminal
2. Select segmentation mode, modify classes, click on save
3. Go to File and click on Set Label Folder, and change it
4. Go to File again and click on Set Point Cloud Folder, and change it
5. Done

Desktop (please complete the following information):

• OS: Ubuntu 20.04.6 LTS 64-bit
• Python Version: 3.11.9
• Installation: pip, on conda environment

Additional context
Sometimes it just works, but I haven't figured out why. It's a really great and useful tool but lately it's just not working :(
Thanks in advance!
