Exception Thrown in Squirrel Updater: FileNotFoundException

[eplewis89]

Bug Description Whenever Postman updates, I can no longer run Postman. This seems to be due to a bug in the updater. The log specifies the the "RELEASES" file is missing when opening Postman. Here's the log:

Expected behavior I expect the app to update properly and start.

App information (please complete the following information):

• Native
• Postman Version 7.2.1
• OS: Windows 10 x64

Hey @eplewis89

I know it's been a while, apologies for that 🙏 - Just trying to find out if this is still an issue that you're facing with the latest app version?

[DannyDainton]

I'm going to close this one out but we can reopen if you're still seeing the issue.
