Fix start App Center with startup mode "both" in demo app

[AnastasiaKubova]

Things to consider before you submit the PR:

• Has CHANGELOG.md been updated?
• ~Are tests passing locally?Z
• Are the files formatted correctly?
• Did you add unit tests?
• Did you check UI tests on the sample app? They are not executed on CI.
• Did you test your change with either the sample apps that are included in the repository or with a blank app that uses your change?

Description

When change startup mode to "both", click the crash and send report, the AC portal can't receive the crash report.
