Uhandled exception on starup

[Void2258]

Describe the bug
When starting up, an unhandled exception is thrown, and the program crashes entirely.

To Reproduce
Start add-on manager.

Additional context
Add-on manger is completely nonfunctional. Upon next patch, without the ability to update arcs-dps, gw2 itself may become broken.

don't forget to attach the config file to the issue
GW2 Addon Manager.exe.config.txt (Had to rename to txt to allow upload)

log.txt

This isn't broken for everyone fyi, so running to reddit panicking was extremely poor form

I posted on reddit before I found (or refound I guess after several years) this github and edited the github link in later.

This is problem on your folder/file permissions that denies acces to update-placeholder.yaml . Fix write, modify permissions on addon, and program folder

What folder? I can't even find this file location. Not sure how any of this got changed anyway; I touched nothing at all. I did take a break between the 2 expansion releases for a bit though, and this happened when I came back.
