"Windows fatal exception: code 0xc000001d" when trying to install PCL plugin

[andrii302]

Good day, I have installed and used CloudComPy without any issues, but when it came to cloud registration I encountered a problem when trying to run following code:

import cloudComPy as cc  
if cc.isPluginPCL():
    import cloudComPy.PCL

I get the following message in Spyder's console:

QFileSystemWatcher: Removable drive notification will not work if there is no QCoreApplication instance.
JsonRPCPlugin::JsonRPCPlugin

Windows fatal exception: code 0xc000001d

Kernel wird neu gestartet...

("Kernel wird neu gestartet" means "restarting the kernel") I am using Python3.10, and the CloudComPy310_20240420 version, with miniconda3 on Windows 10 Enterprise LTSC operating system. When trying to import other plugins the same way, like PCV plugin, I didn't get any error and it runs just fine. Thanks in advance!

Hello, Unfortunately, I can't reproduce this problem on my Windows 11 installation (with the CloudComPy310_20240420 version), either in Spyder or directly from the Python prompt (on the conda terminal). Have you tried outside Spyder? Best regards, Paul
