My friend's calamity mod stopped working

[drowsy gull]

So, after like 6 months, we decided to play again This mod
It worked for me and my other friend, but for my second friend It just doesn't work, like, he installs calamity, Turns on, It's loading, and then crashes

[tight forge]

Verify vanilla and tmod gamefile integrity

[drowsy gull]

He did both, nothing helped

[tight forge]

Do a reinstall

If that still didnt work head to Tml’s server #other-discords

[drowsy gull]

Still doesn't works
He reinstalled whole game many times
And also reinstalled calamity mod many times

[tight forge]
