Just found out that Extra Origins somehow collides with the Lato Origins mod.
Both mods work fine without the other one present.
Other mods are present as well but do not seem to interfere.

Log:
latest.log

Is there a different log? This one doesn't tell me much

Just downloaded it again to force a crash.

The startup log:
2021-04-20-1.log

No crashreport is being generated, and I feel like this one would be the same as the previous log.
Any idea where i can find information that could be helpfull for you?

Someone told me Lato uses an outdated version of Pehkui, I can reopen if this wasn't the cause should they update
