Video won't render

[Qirehtox 0]

Every time I attempt to export a movie, after finding the file location I wanna save it on and clicking 'save' on my Windows 10, this pop-up opens. It's not to do with video length because I've saved longer movies with ease, and the only render options I've touched are the Width & Height of the camera size as well as the Tempo in 'Project'. I've tried saving another movie I've made and that worked, as well as freeing up some computer storage and nay to that as well. This video is kinda important and I really wanna get it out as soon as possible, and any help is so much as worth money for all I care.

99999 Width and 99999 Height is the problem. I would recommend changing the video size to one of the presets like HD 720p or FHD 1080p. The problem with the width and height is that the program tries to render a video that is 99999 pixels wide and 99999 pixels high, which is almost 10 billion pixels per frame and way too much for the program to handle.

Bro why are you trying to render at 99999x99999?
