CIMClassBreaksRenderer not supported, causes crash

[graphikeye]

When loading a style, I receive the following error in the console:

File "C:\Users/xxxx/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\qlyrx\qlyrx.py", line 1601, in run
self.j_data = self.read_lyrx(self.dlg.file_select.filePath())

Can you please edit your issue to provide additional information,
What operating system you are using?
What version of GQIS?
what version of the plugin?
Can you provide the data and .lyrx you are trying to use?

You seem to have been trying to use a currently unsupported symbology type.
Your .lyrx is using CIMClassBreaksRenderer which is still not supported.
You can check out the readme to see which symbology types are supported.

Will keep this issue open under a new name.
A warning message should be added to prevent questions about this.
