pitzDailySteady tutorial error

[Shodhanam]

I have recently downloaded openfoam 11 and I am trying to run the foam tutorial for the backward facing step in the incompressibleFluid, pitzDailySteady but it is showing error. After installing OpenFOAM I ran the command 'foamRun -help' and it ran perfectly. After this I tried to create a directory within the home/openfoam with this command 'mkdir -p $FOAM_RUN' then ran the command :
'cd $FOAM_RUN
cp -r $FOAM_TUTORIALS/incompressibleFluid/pitzDailySteady .
cd pitzDailySteady
blockMesh
foamRun
paraFoam'
After this the operation completed with the message "SIMPLE solution converged in 287 iterations" then it Created temporary 'pitzDailySteady.OpenFOAM', after this I got "QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700" from here I got tons of error messages and at last gor a message saying "Segmentation fault". When i try to open paraview with the command 'paraFoam' it runs some thing but then stops and does nothing. Below I am attaching the screenshots of the errors for your reference, I kindly @OpenFOAM to guide me on how to solve this issue. Thank you.
