It looks like something in the app tried to use removeChild on something where it isn’t the parent. Beyond that, I can’t be sure without seeing the trace or the code.
Someone here may be able to recognize the source of this problem if you share a public repo, minimal reproducible example, or more details from the logs.
I hope it’s working for you now. If not, here are a few things to try:
Try incognito/private browsing mode - This will disable extensions and use a clean browser state
Use a different browser - Test with Firefox or Safari to see if it’s Chrome-specific
Clear all browser data for v0.dev (not just cache) - Go to Chrome Settings > Privacy > Site Settings > View permissions and data stored across sites > Search for v0.dev and clear all data
Disable browser extensions temporarily - Some extensions can interfere with React applications
