The version on Zdoom's site works normally, but I wanted to use a dev build for a mod, and I'm having trouble figuring out what is going on. I tried to find similar issues like mine, found one with the exact problem, but doing the things written on there didn't work. (Moving the gzdoom.ini file to the main folder.) Any help is appreciated. (It's my first time trying to use a dev build.)
My graphics card is Intel UHD Graphics. Processor: Intel Core i3-1005G1
Gzdoom dev build 4.15pre-589-g24e7bee0f works, but doesn't open properly. No window but visible in task manager.

A dev build should work in exactly the same way as regular GZDoom. i.e. it should work if you unzip it to a folder (not in Program Files), provide it with a suitable IWAD and... that's it really.
I don't know your model of graphics card, but Intel cards can be a bit troublesome. However, if you are able to get the current official version of GZDoom working, that probably shouldn't be an issue. Perhaps someone who knows your hardware better can comment more meaningfully on that.
It could be that your antivirus software is doing something with the dev build. If it doesn't recognise the exe, it might be preventing access to it - but if task manager reports it as running, then maybe not.
If you suspect your ini might be an issue, then don't just copy it to the folder, but also call it gzdoom_portable.ini
That will make GZDoom behave like a totally portable installation - it will use that ini file and not try to read from one stored in... wherever the current standard for Windows keeping ini files is (Documents/My Games... I think). This works with official GZDoom too btw - like I said, official builds and dev builds arevery similar, except for the caveat that the dev build is a work in progress (and thereby has features and fixes added since the last official build) and the official build is to release standard.
If you want to confirm which ini your game is using, type whereisini at the console and it will tell you. Of course, you have to be able to get the game to run to do that.
[edit]And just to confirm, I just downloaded the build that you have been trying and fired it up. On my system it started no problem at all. So, that confirms that the build itself is OK, even if it doesn't help you very much.[/edit]

Thank you!! It seems like Windows 11's antivirus doesn't like the dev build. It works now after disabling it. Words cannot describe how satisfied I am right now.

Cool. Glad you got it sorted.
I'm still on Win10 (my PC can't run 11) and quite often I get a dialogue popping up with a new build telling me the dangers of running unknown software and giving me the option to know more (and then continue).
I think it's just that the security software defaults to warning you/not letting the build run based on nothing more than "I don't have any record of an exe with this CRC value" or similar.
