Same on 1.21.8, everything works perfectly on the first launch and without banhammer, but when banhammer is also added, it just breaks after any other startup.

The thing is though, I think ledger should not be fixed, but banhammer... because it literally breaks with so many other mods (from my testing also YAWP and somtimes BlueMap but there might be more)

If i find a fix, i will comment again, because in the BanHammer config you are able to edit what database you want to use. I will check from my older servers and online configs to try to fix it.

I did not find a direct fix, I just ended up compiling the fix/sqlite branch and it works reliable for now

I can confirm that this is caused by the "Banhammer" mode. Specifically, I use "banhammer-0.14.1+1.21.8.jar" and I found a very simple fix, but it only works if Banhammer is used with MySQL DB. Just open "banhammer-0.14.1+1. 21.8.jar" with Winrar and delete "sqlite-jdbc-3.50.3.0.jar" from the "META-INF/jars" folder and save it back as .jar. This way, Ledger will load its jdbc driver on sqlite (not the one from Banhammer, which was loaded first because of the mod name) and Ledger will work.
