I do not know if this is new error in 2023. But solve gives this strange error first time it is called. Second time the error goes away.
Any workaround possible and why does it happen? It happens when kernelopts('assertlevel'=2): is set. But I need to have this set all the time. Same problem when using PDEtools:-Solve. I can't even trap this error since it is internal. So program crash and no way to continue.
eq:=exp(x)*sin(y(x))-3*x^2+(exp(x)*cos(y(x))+1/3/y(x)^(2/3)) = 0;
Error, (in SolveTools:-CancelInverses) assertion failed, simplify should not leak _Z variables out from RootOfs
Finding too many problems in Version 2023 :(
This seems new problem in V 2023? I just tried it on V 2022 on same PC and no error there. First time used no error. Here is V 2022 worksheet. So this seems like regression.
