incompatible numpy version?

[TecDroiD]

when I try to import an stl file I recently used on my 3d printer I get the following message on bCNC:

$ bCNC
new-config bCNC <configparser.ConfigParser object at 0x7fa706f08ed0>
G2Core loaded

np.int was a deprecated alias for the builtin int. To avoid this error in existing code, use int by itself. Doing this will not modify any behavior and is safe. When replacing np.int, you may wish to use e.g. np.int64 or np.int32 to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

... and nothing happens- means, the mesh didn't load.

I use debian 12 and tried the stock version (1.0.14.218 I think) and the current version I can get via pip..
