There is some evidence that older Kijai/KJNodes installations have been involved in this exact situation, so if the search points there, updating KJNodes is the likely fix.
Ultimately though what you are likely dealing with is a ComfyUI installation with custom nodes that has gotten messy and is running new and old stuff that do not work together. It's not unlikely that this old workflow has some old stuff in it.
If you wanted to try to find which node, IU'd start by muting/bypassing the LayerUtility: PurgeVRAM V2 or replacing it with LayerUtility: PurgeVRAM
