Hi, @gitXite. I'm Dosu, and I'm helping the desktop team manage their backlog and am marking this issue as stale.

Issue Summary

You reported that a recent desktop update broke your ComfyUI setup.
Existing workflows no longer run, including the Flux2 template workflow.
Fresh installs and reinstalls also fail during startup/installation with a hostbuf_allocate not found error.
The behavior appears to affect both migrated and clean environments, which suggests a broader compatibility or packaging regression.

Next Steps

Please let us know if this is still happening on the latest version of the desktop app.
If it is still relevant, you can keep the discussion open by commenting here; otherwise, this issue will be automatically closed in 7 days.

Thanks for your understanding and contribution.
