Trying to find out how to downgrade codex desktop because every single time I try to do anything after updating to this latest version I see this error without fail:

Invalid Value: 'tools'. Function 'functions.spawn_agent' declares encrypted parameters but is not configured for encrypted tool use by this model.

It happens if I send any message at all
