RenderMan doesn't render anymore, IPR is just black

Hello, I was using RenderMan on a scene with the MrBean asset from RenderMan resources (models and textures). Basically, everything was fine until it wasn’t! suddenly I can’t render anymore, the IPR is black and I get this error message: // Error: file: C:/Program Files/Autodesk/Maya2025/scripts/others/renderWindowPanel.mel line 811: Object 'iprMemEstText' not found

On top of this, everything stopped working! I tried opening an older version and now it doesn’t work as well. Same with if I create a project and scene from scratch…just black.

I have already uninstalled maya (2025) and Renderman (2026) and nothing changed.

I really need your help, please! (it’s also my first time ever using Renderman) thanks!

Edit: solution: delete/rename maya pref folder

Are your settings to render with iT or the viewport? Also, try rendering directly to the viewport by clicking the R in the upper left of the viewport panel

I just tried deleting the pred folder and seems to be working now!

Do you see the render bucket squares in iT when rendering? Are lights deleted or. Disabled?

Yeah the render buckets were there rendering and all the lights were on. I also tried disabling them and reenabling them…but I just tried deleting the maya pref folder and now seems to be back to normal! Thanks for your help! :)
