I remember this issue I had in 22, so it’s a mod conflict which causes LUA error and shows below the map, please check mods and identify that conflict may be from logs !

500? You may want to thin out your mods a little(lot) especially if you're having conflicts. You should go to the FS25 page on discord (https://discord.com/channels/299449702599098368/1356202399563251722) and ask there. They have some Giants moderators who are really helpful answering questions. They will require your log file and any screenshots of the issue you may have.
