How can I stabilize the matrix left division (i.e. "\")?

I have a problem using the matrix left division operator (i.e. " \ ").
In particular, it happens to me that if I apply the operator on the same matrix and using the same Matlab version (2023a) but using two different PC, I obtain two different results.
I think that the problent could be that I'm working with a singular matrix. However I'd like to find a way to solve the calculation obtaining the same results even if I use different PC, maybe forcing the same settings of the operator.
Can you help me?

You cannot. You must regularize the problem somehow and make the matrix non-singular.

Try pinv, lsqminnorm it can stabilize somewhat the inversion with (near) singular matrix. Both bave a tolerance argument to tune the stability?
