Progression blocker - Scar not in X17

[-P|T- DxeeL]

Spoilers ahead for anyone not at this point in the game
So after I killed Faust and headed back to Malachite, I got the mission to speak with Scar in the X17 laboratory, after a long trek on foot I got back to the base and took the elevator underground only to have him not spawn in the game. I'm completely stuck at this part and I wanted to finish the game this weekend, is there any workaround or anything I can try? I fast traveled, reloaded saves, went and explored and came back and nothing seems to fix this. I was contemplating doing the whole Faust boss fight again, but that was such a slog and a pain to try, at this point I'm not even sure it's worth it. If anyone can offer any helpful advice I'd appreciate it.

I've found a solution that worked immediately for me and other people who do not wish to wait for an official fix from GSC in the meanwhile.
1. Download the UE tools for Stalker 2 from Nexus mods https://www.nexusmods.com/stalker2heartofchornobyl/mods/64?tab=posts&BH=6
2. Follow the installation steps, basically you need to unpack the contents of the zip and paste them to the game game installation folder and follow the path: "...\Stalker2\Content\Paks";
3. Once you reach "Paks" directory, make sure that "~mods" folder exist. Create it if it doesn't;
4. Move UETools files you've unpacked earlier so they're inside of "~mods"
5. Launch the game and reach Malachite.
6. When outside of the Malachite base, press F10 for console, type XStartQuest E09_MQ01, this should re-run the dialogue with Scar telling you to meet him in Malachite, going to the quest marker after the command, he was spawned in, and I could progress.

Had the same trouble post 1.02 patch, but this unlocked my soft lock on this mission!
This could work on other unstartable Main quests as well, can't thank you enough...
