Mewgenics Crashing On Launch Fix
If Mewgenics is crashing on launch or freezing on the rotating neuron loading screen, the problem is usually a Windows compatibility or fullscreen optimization issue. In most cases, the game is not actually broken. It is getting blocked or stalled during startup.
The most reliable fix is changing the .exe compatibility settings directly, not just running Steam as admin.
Here is the full startup crash fix guide.
Fix 1 Disable Fullscreen Optimizations And Run As Admin
This is the fix that worked for the highest number of players.
Do this exactly:
Open Steam
Right click Mewgenics in your Library
Click Manage
Click Browse local files
Find Mewgenics.exe
Right click it and select Properties
Open the Compatibility tab
Check Run this program as administrator
Check Disable full screen optimizations
Click Apply
Click OK
Launch the game again from Steam.
Do not skip the fullscreen optimization step. Just running as admin alone does not always fix it.
Fix 2 Do Not Click The Game Window
If the game is stuck on the neuron loading screen, do not click it.
Clicking forces Windows to mark the app as not responding, which can immediately crash it. Some users reported the game eventually loaded after several minutes if left alone.
If it looks frozen:
Launch the game
Do not alt tab repeatedly
Do not click inside the window
Wait 5 to 10 minutes
It may load on its own.
Fix 3 Clean Reinstall With Restart
If the above does not work:
Uninstall Mewgenics in Steam
Fully restart your PC
Reinstall the game
Apply the Compatibility fix again before launching
Some users reported the game randomly started working after reinstalling.
Restarting the PC before reinstalling is important.
Fix 4 Update GPU Drivers
Outdated drivers can cause launch crashes.
Update Nvidia or AMD drivers
Restart your PC
Launch the game again
Even if drivers seem current, reinstalling the latest version can help.
Fix 5 Temporarily Disable Antivirus
Some antivirus programs block new game executables at launch.
Try:
Temporarily disabling antivirus
Adding Mewgenics.exe as an exception
Launching again
If it works, re enable antivirus and keep the exception.
Fix 6 Install On Main Drive
A few users tested installing on different drives. If you are running from an external or unusual drive:
Move the install to your main drive
Apply the Compatibility fix again
Launch
What This Is Not
This does not appear to be a hardware power issue. Players with GTX 1660 Super and similar mid range systems experienced it. The game is designed to run on older hardware.
It is almost always a Windows launch conflict.
Final Blurb
If Mewgenics is crashing on launch or freezing on the neuron loading screen, start with disabling fullscreen optimizations and running the .exe as administrator. That is the most consistent fix.
If it still freezes, do not click the window. Let it sit. If needed, reinstall after a full restart and reapply the compatibility settings.
Startup crashes are frustrating, but this issue has been resolved for most players using the steps above.
FAQ

Windows may force close the app when it thinks it is not responding. Clicking can trigger that.
Does verifying Steam files fix it?
Usually not by itself. The Compatibility settings fix is more reliable.
Is this a GPU problem?
Not typically. It affects a wide range of hardware that should run the game fine.
What is the most reliable fix?
Disabling fullscreen optimizations and running Mewgenics.exe as administrator.
