The game not loading at all, and your character and world being corrupted, are two different things. Not sure why your game wouldn't load at all. You're saves could be changed by the mod, which might prevent loading - it's a pretty bad mod if it's done this.

You could try disabling all the options in V+ back to vanilla if you can, then loading your world and character. If the mod has any sanity it should (hopefully safely) remove it's crude off your save files since it doesn't do anything anymore, then you should be able to close valheim and remove v+. I have no idea if this actually works, if not V+ is a worse mod than I realised.

Did you remove something that doesn't belong to the mod? Have you tried reverifying your game files?

I'm not sure how you do it manually, but using Vortex, I was able to easily disable the mod when I was on the test branch. I did lose some stuff in my expanded chests, but other than that the save was fine. So V+ shouldn't be screwing up your save files that badly. (Although it could depend on which options you had turned on. But I'm not sure which ones would be so bad that you couldn't get it started.)

copy mod's instructions in a text file

already looked there, sorry, no help

found this page, still it does not say how to uninstall to where the world and person remain

This is how I've always done it. Remove the valheim+ dll from the bepinex plugin folder

You don't?, that mod is baked into your save files.

I believe you can remove the dll file that is in the BepinEx folder. The server admin that I was wanting to play on looked it up and told me "go to your valheim folder and look inside BepInEx/Plugins and delete the .dll file" This worked for me.

Rule #1: when you install a mod, copy mod's instructions in a text file for later. Even better, but it's up to personnal taste, write a small summary of what the mod does.
