What is your operating system?
W10 Home N x64
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
21.05.18 / No
Can you repeat the problem? If so, what are the steps?
Apparently Shotcut does not allow the colon character ( : ) within the name of a new project, but the error message shown is very misleading. I think it could be a little bit enhanced so that the true reason comes out. I have attached a snip and the log.
