Quick Synapse fix for stuck loading issues.
Instructions:

1. Copy the following code between CODE and END into a new notepad.
2. Go to File > Save As... > Save the file as autofix.bat (you can name it anything as long as you ensure you add the ".bat" at the end of the file when saving)
3. The file should look like a box with gears, if it's a text file, follow the 2nd step more closely.
3. Save the file to your Synapse folder that contains the Synapse program*. If you saved the batch file somewhere else then just move it into your main Synapse folder.

*This folder should contain the synapse.exe, synapse-x-x-x.bin files, x64, x86, autoexec, scripts folder, etc.

In other words, Just put the fucking bat file into the folder where you open synapse, ok? :)

4. Right click and execute the bat file as ADMIN

CODE
------------------------------------

@ECHO OFF Working...
TASKKILL /F /T /FI "IMAGENAME eq synapse*"
TASKKILL /F /T /IM "RobloxPlayerBeta.exe"
CD %appdata%
RD /S /Q SynapseAuth
RD /S /Q SynapseData
TIMEOUT /T 2 /NOBREAK
IF EXIST Synapse.exe. DEL /F /Q *.bin. ELSE echo filename. not found
TIMEOUT /T 2 /NOBREAK
@ECHO Relaunching Synapse...
Synapse.exe
Pause
@ECHO Done. Press any key...

END

Explanation:

This simply terminates both the Roblox and Synapse processes if any are running in the background, then deletes the appdata folders for a fresh re-creation, then it will delete the old .bin backups if found (only will occur if ran in the Synapse folder, if it is not then it will be skipped). It will relaunch Synapse (again, same rule applies, only if launched in the same folder as Synapse). Otherwise, just relaunch Synapse manually. Hit any key to close the console.
