.exe file stops and eventually starts after building in QtCreator?

I made an application using Qt in QtCreator. Recently, I noticed there's a persistent yet inconsistent occurrence of a problem. When I build it, whether it is release or debug mode, the program gives an error as shown in the following images

Then without even without any response from me, after a few seconds, the dialog closes and program eventually starts. This occurrence doesn't always happen, sometimes it does, sometimes it doesn't.

I'm not sure if these issues are relevant, but I also notice the following issues in the Application Output window of Qt Creator:

Exception at 0x756a1d4d, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) in SPVC32Loader

Exception at 0x756a1d4d, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) in SPVC32Loader

Do you have any idea why I'm having this problem?

Thanks

SPVC32Loader appears to be a browser hijacker. I would suggest you verify if you have this dll in your system and then removing it. Here is a relevant link.
