How to fix LSOpenURLsWithRole() failed with error -10810 on launching GlamorousToolkit.app?

[Dima-369]

macOS 10.14.6 Glamorous Toolkit v0.8.1668 beta (Mac Intel version)

$ open GlamorousToolkit.app
LSOpenURLsWithRole() failed with error -10810 for the file /Users/Gira/Downloads/GlamorousToolkit-MacOS-x86_64-v0.8.1668/GlamorousToolkit.app.

I tried the following to fix it but without success (from https://apple.stackexchange.com/questions/181026/lsopenurlswithrole-failed-with-error-10810-cant-open-install-os-x-yosemite), it is still the same error:

$ chmod +x GlamorousToolkit.app/Contents/MacOS/GlamorousToolkit-cli
$ chmod +x GlamorousToolkit.app/Contents/MacOS/GlamorousToolkit
$ xattr -dr com.apple.quarantine GlamorousToolkit.app

Does anyone know of a fix?

I also tried to use the following which by the way failed (but that is another issue) and the present GlamorousToolkit.app gives the exact same error.

curl https://dl.feenk.com/scripts/mac.sh | bash

Here was a somewhat similar issue, but my error code is different and I do not have any Anti-Virus software: https://github.com/feenkcom/gtoolkit/issues/1733

This is intended behavior by Apple. Stupid, but intended. Move the application out of downloads.

The answers to the question on stackexchange are wrong for current MacOS versions

Thanks a lot. This did indeed help. But now Glamorous Toolkit crashes after picking the GlamorousToolkit.image file. I'll create a follow-up issue.
