The mods usually stop working when the user launches Beat Saber, and no mods or custom songs are shown in the game. The problem also arises after an update of Beat Saber as the mods are not officially supported on Beat Saber Before moving on with the solutions to mod Beat Saber, try to run your game without any of the mods and then with the mods if the issue arose after an update of Beat Saber.
Solution 1: Allow the Beat Saber Related Traffic through Antivirus/Firewall
Your antivirus and firewall applications play a pivotal role in the security of your system and data. But the mods may fail to work if the firewall/antivirus applications of your system are blocking access to a resource vital for the operation of Beat Saber. In this case, allowing the Beat Saber-related traffic through the antivirus/firewall applications may resolve the issue. Warning: You may proceed at your own risk as editing antivirus/firewall settings may expose your system and data to threats like trojans, viruses, etc.
Solution 2: Re-Patch Beat Saber for Modding
Mods not working in Beat Saber could be a result of a temporary bug of patching (which allows modding) of Beat Saber. The error could occur, especially if the Beat Saber game was recently updated. In this context, repatching Beat Saber may solve the problem.
Solution 3: Verify Integrity of the Game Files of Beat Saber
The files of an application/game could get corrupt due to many factors like sudden power failure etc. In the case of Beat Saber, the corruption of the game files could not be ruled out if you are using mods. In this context, verifying the integrity of the game files (which will rule out any corruption and compatibility issues of files) of Beat Saber may solve the problem.
Solution 4: Reinstall the Mod Assistant for Beat Saber
The mods issue can arise if Beat Saver is recently updated, and the mods you are using are not compatible with the latest version. In this context, installing mods through the Mod Assistant (again) may solve the problem.
Solution 5: Reinstall Beat Saber
If nothing has worked for you, then the mods issue could be a result of the corrupt installation of Beat Saber. In this context, reinstalling Beat Saber may solve the problem. If nothing has worked for you so far, then wait till your required mods are updated to be compatible with the updated version of Beat Saber. If you can revert to the older version of Beat Saber, try an older version of Beat Saber. Also, check if you can get rid of the issue by setting up Custom UI with the mod assistant.
