Saw someone mention this on one of the mod pages in a post a few days ago. I'm now experiencing this too, once I pass 16 mods (5 native and 11 I installed) the game crashes on start up. It doesn't seem to matter which ones I have installed, any combination of 16 mods seem to work but as soon as I put in a 17th the game crashes. This is only when its showing more than 16 in the Mods tab on the launcher. For example i have Bannerlord BannerEditor Enhancer, which I believe just edits some files and doesn't show up on the actual Mods tab and it works fine with 16 others. I asked about this on Reddit too and have responses saying they have 20+ mods enabled so just wondering if anyone else is having this issue and if there's a possible work around for it.
