Undefined Error after patch 4.12.20

I have faced with some problems. Today, September the 7th , Robocorp released new version - 4.12.20.
It is impossible to open Robocorp after it . I cant fix this problem (spawn cmd ENOENT)

Hi,
Checking the issue report now…

The log is showing that the (Windows long path support](https://robocorp.com/docs/troubleshooting/windows-long-path) is not enabled on your machine.
…which might be one source of problems.
Are you getting the initial check-up view when starting Lab, and can you use that to fix the problem?

But the error seems to come from a corrupted recent robots listing, I would like to see the target file but as it contains your data I’ll ask that via the issue ticket.
…and post the actual fix / reason back here once we’ve figured out what’s going on.

Thanks, for the report.
Br, Kari
