My workflow is to have ANSYS Fluent 2021R2 write Ensight Case Gold files that i then post-process in paraview. I could successfully do this before with a different simulation (the ANSYS Fluent version and paraview version are remained the same), but for some reason, when i try to open my *.case file with this simulation, Paraview 5.10.1 spits out this error.
I am running a parallelized version of paraview but this error is also given when i run paraview on a single core. After doing some digging online, several people have encountered this issue. I have also applied the fixes to the encase/case file described in this thread.

If i write the same Ensight file but in ASCII (as is an option that ANSYS Fluent provides), i can successfully open it. I prefer the file in binary because it’s smaller and will potentially open up faster.
EDIT: This issue also seems to be captured here.
