Export the log so that we can read this without having to zoom in on a screen shot
Whats the issue here exactly? Is your game crashing? is it slowing a lot?
It looks like the game is choking on loading some plant/grass textures, if you scroll to the top of the log it will probably tell you what mod is causing the issue, have you removed any mods since you started the save?
I think you might be misreading the log, nothing got deleted, "duplicate stacktrace" just means the same error already showed up higher in the log so it's not printing the full trace again. Your save loaded, your colonists are all there. It's just certain plants failing to spawn, which is almost always a mod you added/removed/updated. Scroll to the very first red error with that same ref code and it should name the mod
