ERROR: LAPACKException(4)

Can someone explain what this error is about? and what could be possible solution?

I can’t share my model but it is differential equations based and have equations such du[1] = a*(b)^n * c*(k)^m + a*b. So, it contains equations with power and there i’m using NaNMath.pow(b, n) to avoid negative inside power. Another thing is parameter values and state values varies from very small 10^-20 to 10^8 (so very low to high).

I can see that it comes during solving differential equation but why?
Before this I had Error: Singularity (6) and for which I used linsolve = QRFactorization() in my solver.
