This appears with SageMath 9.5 only. A temporary workaround is to downgrade SageMath to <=9.4, e.g., mamba install sage=9.4.

I have run into the issue with importing sage.all. This solution is not working for windows. Anybody had any success in solving this on windows10? Looks like sage installation on windows isn't possible unless using it through a ubuntu subsystem (WSL).

I just noticed Sage has discontinued their Windows binaries. It seems WSL or installing from the source are the only two options for Windows users. @Rifahaziz have you managed the situation? If so, it would be very helpful to share your experience!

Tested PASS with sage=10.0 on Linux, with 9316511.
