import fail: SyntaxError: invalid syntax

[SomaLily]

I installed manim by conda install -c conda-forge manim. Imported manim and ran some examples on jupyter notebook successful last day, until raised dvisvgm not found. Then I installed and updated some depends for dvisvgm include Clipper2, FreeType2, Ghostscript, Kpathsea, potracelib, ttfautohint, woff2 , brotli , xxHash, zlib. Finally make install dvisvgm , and manim.NumberPlane().add_coordinates() run OK. But the other day (today), when import manim , it went wrong:
