Are you having any character / animation mods installed?
Try a different resolution. Technically there's no way that this can be resolution related but we had other glitches in the past that were caused by certain video settings

No mods, clear install. After train section I noticed that some NPC or invisible or rainbow DEAD sign. I met softlock when guard that gives a gun, he is DEAD sign and his magazine flying higher than chair.
Native resolution is 1440x900

This looks like some assets are missing... Even tho this should not happen even if some BM:BS files are missing you would get the default character models from BM as a fallback.
Have you also checked your custom folder in your gamedirectories? (bms and bshift)
Only thing I can imagine that content mounting messes up with asset loading.
On what OS are you playing?

Win 11, custom folder doesn't check

Can you please tell me if the following files are in your bshift folder
bshift_models_000.vpk
bshift_models_*.vpk (* means 001, 002, 003, etc...)
bshift_models_016.vpk
bshift_models_dir.vpk

And are there any other models missing except character models? For example in the Area 3 lobby or the security cameras.

Are you using a symbolic link or a local installation in you Black Mesa folder?

Only characters, they or missing, or T-pose or... how to say...destroyed(I saw on CCTV NPC looks like a bunch of triangles), I use install from steamapps\workshop\content\362890\2424633574, check, unistall, put files in-game folder, install and stiil like that, then I downloaded version from google drive and still this happening

By in-game folder I assume you mean putting the bshift folder into your Black Mesa directory and by google drive I assume you mean the ModDB download (?)
These are identical tho, except the steam varaint has the symlink.
Sadly this is a very uncommon issue I also see the first time, however I assume that something on your end causes specific data not to be loaded. (Usually our new character models and animation libraries)

Maybe try verfy your game files (Right Click on Black Mesa in your Steam library => Properties => Updates => Verify Integrity of Game Files

Important is that you are playing on the latest public Black Mesa version (1.5 Necro Patch) and you don't have any mods installed / in your bms or bshift custom folders

Verifying files doesn't help, playing on 1.5 Necro Patch

Found fix, use symlink and this now working without any models and animation issues
Thinking my stupidity kicks in x)
