How to solve the error caused by providing beam end releases?

Answer:

1) check if the material had very high elasticity. Such high values can result in instability. Kindly reduce this stiffness to a magnitude of 10^8 kN/m^2 if it is high.

Change the elasticity as shown below.

2) If the magnitude of the moments is quite low, Delete all the beam end releases.

3) If it is to be further reduced, just reduce the section size to say 2mm. Change the section size as shown in the image below:
