The fluuent application cannot be started through workbench but it can be started separately in win64 folder. I reinstall Ansys several times but still don't work. Every time I delete the relevant system variables. The Ansys version is 2023R1, I use Win11 system. The first time this issue started because I modify "udf.dat" .
