i don't know why but when i try to run it gives me an error. heres the pic of the error:

im running gzdoom 3.7.2 version if it helps

also i don't know if its ok to post like that as its my first time using itch.io at all so if i did something wrong im sorry

Thanks for the report, no problem! This issue has been seen by other players, and it's a bug with the current version of GZDoom: https://itch.io/post/663685

GZDoom's developers fixed the bug, but I'm not sure when a new build of it with that fix will be out. In the meantime, if you don't need features from the very latest GZDoom you could try using an older build of it from the 3.6 series.

Same thing happened to me on Delta Touch 

GZDoom 4.0 was just released, and fixes this: https://forum.zdoom.org/viewtopic.php?f=1&t=64188
