Yes, I have experienced this, where I can just reload, which has not been a major problem.
However, the issue persisted even after reloading and trying different browsers. Upon investigation, I discovered that the error stemmed from an avatar component to which I had made some updates.
After these updates, all pages and elements containing this component failed to load, and my button components appeared disabled during the preview. To address this, I resolved the problem by deleting all instances of the problematic component.
The last modification I made to the avatar component was adding a size attribute that impacted multiple classes on the component, specifically named 2XSmall, XSmall, Small, Medium, Large, and XLarge. I'm unsure if the naming of these classes might have triggered the issue.
