打开控制台还能vuedevtools就报错

@tks-007 please update Vue, looks like you are on an older version.

Is this related to Vue version? I had to use Vue2 and Vue3 in a single page since I've used micro frontend

I have the same issue. We currently have a mix of Vue 2 (2.6.14) and Vue 3 (3.2.31) components.

The beta version of Vue Dev Tools (6.0.0 beta 21) does not have this issue, so I have reverted back to the beta again.

this works. Issue should be closed, I think

Seeing the same issue on Vue DevTools 6.1.4. Vue 3.2.31 and 3.2.37. Hundreds of repeated console errors. Reinstalling didn't help. Any updates on it, @Akryum?
