java.lang.NullPointerException: Cannot read field "internal" because the return value of "org.zeith.hammerlib.api.config.ConfigHolder.getCurrent()" is null

Stacktrace points to HammerLib. Without more evidence that this is tinkers, going to have to close as a hammerlib bug as I see nothing there that says tinkers is related. Did you try testing without tinkers?

You also are missing the bottom of the crash report.

Also, when reporting issues to multiple mods, helpful to link the two issues, as that makes it easier for devs to communicate

Fixed by updating JEI to the last available BETA for 1.18.1 JEI-1.18.1-9.4.1.112. Odd that the pack ran fine for weeks and only crashed when I updated Tinkers to the newer version today. Seems others were getting a similar crash with other mods (Pnuematicraft etc) but it was JEI that needed to be updated to this latest Beta version.
