Probably need recompile/ update to latest version. Can you please check ? :)

Thanks

I need more details. What is not working? What do logs say? What version of KIS do you have?

Inventories are showing with bit smaller grid and cannot be interacted with. Inventory menu on kerbals in eva is also not accesible. they only tend to use local stock inventory. Moreover parts that have inventory - cargos- are not accesible neither from build nor from use inventory - you cannot transfer items between them. I can paste my log here but it is quite large.

KIS is latest build from repository sadly it does not have version file inside.
KSP.log
ModuleManager.log
MMPatch.log

[edit] there was though interesting moment when my pilot was unable to use eva jetpack and suddenly while browsking i found ut he had 3 bottles of monopropelant on him... i could not do anything with them (not even place them in other similar containers) so i dropped them on the ground - it didn;t show up in mass on hud but after i dropped them he started to fly :)

Well, from the log I don't see any KIS related errors. It looks installed right and the binary is indeed functional. I think the problem is that you have a heavily mudded game and some of the mods are crashing:

[ERR 17:18:46.231] AssemblyLoader: Exception loading 'InterstellarFuelSwitch'
[ERR 17:18:46.255] AssemblyLoader: Exception loading 'PhotonSail'
[ERR 17:18:46.267] AssemblyLoader: Exception loading 'KSPInterstellar'

Try removing them and test again. If the problem still exists, please add images/video and the new log. I also suggest to try it on the pristine game. Of course, most of your vessels won't load, but at least we'll identify if it's the game or the gamesave issue.

Also, do you use upscale/downscale setting on your video card? What's the screen resolution? Do you use UI scaling in KSP?

newest versions - i cannot interact with normal items unless it is in build time with kis parts. I do not upscale anything. I work on normal screen resolution full screen window(aka unity full screen) 1440p

I do not remember touching anything on screen scaling in ksp. I updated few mods to newer versions as they come. B9 part switch is still for 1.12.2 and it is causing warnings, also remove empty tech tree nodes is for 1.11 but i doubt it will collide here.

Given the provided screenshots. Why do you have the stock inventory dialogs open? KIS and the stock inventory are two completely independent systems. They don't cooperate and don't interact. You cannot move items between KIS and the stock inventory (and it was clearly stated on the KIS forum). By a chance, can you make a video to give a better look at the problem?
