I can't start the game

[Blueshroom801]

Whenever I press Play, the button will turn into the Stop button like it usually does when I start up a game. Nothing will happen for a few seconds, and then the button will revert back to Play.
Sometimes I'll get a black screen for a second or two, but then I'll end up in my library again.

I already have both portal games installed on my PC, I've validated the game files, I've moved the portal 2 bin files to the aperture tag files, and I have restarted my PC. I've tried every suggestion that I've read and none of them work. Does anybody else have this issue and have any other suggestions?

Not sure if you are on Linux but I solved it this way:

Downloaded http://archive.ubuntu.com/ubuntu/pool/main/g/google-perftools/libtcmalloc-minimal4_2.5-2.2ubuntu3_i386.deb and then did the following:

Installed dependencies with

sudo dpkg --add-architecture i386 && \
sudo apt install ./libtcmalloc-minimal4_2.5-2.2ubuntu3_i386.deb libgtk2.0-0:i386 libcurl4:i386 -y

(Executed this in the same folder where I had downloaded the libtcmalloc-minimal4_2.5-2.2ubuntu3_i386.deb)

Made sure Portal 2 is installed and copied its bin/ folder to Aperture TAG's folder:

cp -avr ~/.local/share/Steam/steamapps/common/Portal\ 2/bin ~/.local/share/Steam/steamapps/common/Aperture\ Tag

Then ran Aperture Tag with Steam Linux Runtime.

Detailed log of my journey below:

I have Portal, Portal 2, and Aperture Tag installed. I try to run AT, nothing happens. It shows game status as "launching" for a second, but then nothing. Same problem with "Thinking with Time Machine", another Portal 2 mod. Rexaura (a Portal 1 mod) though runs just fine. I tried verifying integrity of game files for all the games. Nothing. I tried switching compatibility tool from "Steam Linux Runtime" to different versions of Proton. Nothing. But now game status changes to "launched" as well but only for a couple of seconds.

I go to ~/.local/share/Steam/steamapps/common/Aperture\ Tag and find portal2.sh and portal2_linux there.
portal2_linux outputs:

 ./portal2_linux: error while loading shared libraries: libtcmalloc_minimal.so.4: cannot open shared object file: No such file or directory 

portal2.sh outputs:

I download libtcmalloc-minimal4 for i386[archive.ubuntu.com] and do

sudo apt install ./libtcmalloc-minimal4_2.5-2.2ubuntu3_i386.deb

Now portal2_linux outputs

Now I do

sudo apt-get install libgtk2.0-0:i386

Note that it requires i386 architecture to be added with

sudo dpkg --add-architecture i386

I had already had it added even before the previous step, but whatever. Anyway, portal2.sh still outputs the same but portal2_linux gives me this:

So I run

./portal2_linux -game aperturetag

and it actually launches the game but it crashes after the "BLINK VIDEO" logo and a short glimpse of the background that is displayed during level loadings.

At this point running game from Steam with Steam Linux runtime results into the same crash after logos as the portal2_linux -game aperturetag does.
