Hi,
Please, try one of the examples of the Fritzing simulator: File->Open Example->Simulator
This error indicates a problem in the package (not finding the ngspice library) and you should report it to the package maintainers. Note that it works well in the official binary. This error has been also reported in other unofficial Linux packages, but it is not a Fritzing bug (well, except that Fritzing should not crash), see: First time use with problem - #15 by vanepp
However, please, note that the simulator only works for DC analysis and transitory analysis (in beta). For more info on the simulator capabilities, check:
https://blog.fritzing.org/2022/06/27/Simulating-Circuits-with-Fritzing
And check this thread to see the transitory analysis:
