I am getting the same problem.

error Invalid regular expression: /(.\fixtures\.|node_modules[\]react[\]dist[\].|website\node_modules\.|heapCapture\bundle.js|.\tests\.)$/: Unterminated character class. Run CLI with --verbose flag for more details.

Wasim, I found a correction that solves the problem for testing. Alternatively you can downgrade to 12.10 Node.js. if you google first line or so of the regex from error you should find the correction in Stack Overflow article.

Closing this issue as a duplicate of #1074.

I face this problem too. Install lates node 12.16.1 does not work, 12.10 and 12.13 do not work either.
