After updating matlab to R2019a, my matlab cannot solve AX=b.

Greetings,
Currently, I am building an improved primal-dual path following algorithm. I need to solve a AX=b matrix equations, where A is a singular matrix. Because the defition of primal-dual path following algorithm, it is very hard to avoid the singular matrix.
When I used matlab R2018 version, although the condition number of A is inf, I still can solve X = A\b and get specific number. However, after I updated to matlab R2019a, I will get X = [nan ... nan] if I solve X = A\b same for X = A^-1 * b and X = inv(A) * b.
It is very important to my research and I have finished half of my project. But now I cannot repeat my work.
Could anyone help me? Thank you very much!
