Steps to reproduce the problem:
1. python chrome-bisect-builds.py -a win -g 486062 -b 486073 --use-local-cache --verify-range -- --no-first-run --disable-default-apps --force-device-scale-factor=1 --start-maximized youtube.com regex101.com
2. Close the browser window that opens
3. Now back at the command prompt choose 'r' for retry

What is the expected behavior?

What went wrong?
It looks like the bisect script is marking the zip file for deletion so that when it is closed it is deleted and can't be re-opened. See the process monitor attachment that shows that happening.

There may be a second bug because if I attempt to retry 486073 it for some reason looks for the 486062 zip.

The same thing happens if I do it the next build, for example if I say 486062 is good and then it starts up 486073, and I close that window and ask for a retry it tells me it can't find 486062 zip.

Did this work before? N/A

Possibly related, I just filed 783353 because I would like to cache the download builds. Often times I have a bisect and I would like to run it again with certain switches just to see if it behaves the same. The initial two builds being downloaded usually holds things up for me.
