Godot is removing entries from Input Map

Vid :
(when I circle mouse around "h" action, I'm actually pressing H on keyboard, but there's no way to see, because nothing happens. Event seems to never be even saved, even if it shows on list of events until project reload)

*removed parts containg my desktop.

Megalomaniak Right, I forgot to mention version. It happens on v3.4.2.stable.official [45eaa2daf]

I must be missing something obvious, or there's some bug.

Video finally finished processing (it took it way more time, than usually)

I will be downloading 3.5.1 right now, to see if it fixes anything.

Edit : Problem persists on 3.5.1 I'll look through all project settings carefully...

When I had this problem initially I just created new project and avoided this problem for long time. But today it struck me again. I found my old post to find how to fix it but it turns out I had no solution simpler than copying all nodes and settings into completely new project...

So - today I decided to fix it without creating new project. I tried to add new input "manually" in "project.godot" file and program detected it, because I got prompt. I've choosenn "reload project from file", the input remained not-deleted for a while, but after 4-5 seconds it got deleted. I was astonished as to how does it recognized that THIS is new input and deletes only that... I tried placing new inputs in different places (so it's before older input codes) but program always knew what's new and kept deleting it!!

I figured it must have some values cached so I decided to delete "project.binary" or something named like that.... That action fixed the over-writing of my changes... Apparently it is another file that stores project data? And apparently it works weirdly... Also I was not able to create project.binary to further study this bug. I tried saving project, changing some stuff and saving project, running project, running project in html, exporting project closing and re-opening editor... Project.binary was not created again despite me wanting to check it's behavior. I'm not even absolutely sure I remembered exact name of file, but I'm 90% sure it was "project.binary"... I deleted it with shift, so I can't even check in trash... Probably shift-deleting file I have no idea about is not the safest way to try and alter something in project, but I got lucky this time.

I can not, I have no idea what causes this bug. I try to track it down since over hour, because what I did was actually not a solution - now I'm unable to save data from inspector... When I click "output" in bottom-bar I see it detects changes to title of dialog window, I then press ctrl+s to save scene including dialog window and it thinks it saved it, but when I close and open scene nothing is saved.......

I made sure I have disk space, I am logged as user "a" , run program and own project files with same user "a", so it's not system permissions issue... I'm starting to lose my mind. But deleting project.binary removed one problem and caused another problem instead. Now I can add/remove input actions freely, but object inspector just doesn't save anything.

I also ran godot from console and saw no interesting prompts that could hint anything.

I now deleted all user data and editor data - so I'm having like clear godot installation, I deleted every file in project that does not contain information written by me (.import s mostly, but some other files too) - and problem still persists, so ... I'm kind of sure the problem is somewhere in project folder... I tried again running it from console with --verbose and --debug flags, but still it didn't print anything worrisome... But it doesn't work.

To reproduce bug I just unpacked this minimalistic project and edited title of popup window. It won't save... Changing other properties of dialog causes title to be saved correctly - along with that changed property, but it's unacceptable anyway, because I wouldn't want to rely on luck for my edit to be saved.
