export HOUDINI_DISABLE_OPENFX_DEFAULT_PATH=1

Add it to your houdini.env file for a permanent solution. houdini_disable_openfx_default_path

Set this variable to 1 if Houdini crashes or slows down during startup due to a buggy or incompatible OpenFX plugin installed in the default system path. It forces Houdini to only load OpenFX plugins from paths explicitly specified in HOUDINI_OPENFX_PLUGIN_PATH , giving you full control and avoiding problematic system-wide plug‑ins. houdini_disable_openfx_default_path
