Describe the bug

Blizzard just enabled addons on the Shadowlands beta and I wanted to test out some WeakAuras. I had copied over my live folders, but was getting an error so I did a fresh install. I get a LUA error upon logging in. I cannot open WeakAuras. Note that the below error log is best that I can get as BugSack and BugGrabber seem to be broken as well.

Do you have an error log of what happened?

Steps to reproduce the behavior:

Login

Screenshots
Not sure if needed, but I can gather one for you if that helps.

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?
Everything is disabled except for WA, WA Archive, WA Model Paths, WA Options and WA Templates.

Which version of WeakAuras are you using?
2.17.12

Are you on World of Warcraft Classic or Retail?

• [] Classic
• [] Retail
• Shadowlands Beta - version 9.0.1.35213

Was it working in a previous version? If yes, which was the last good one?
Not to my knowledge

Additional Info

I have no WeakAuras setup at the moment as I wanted to make sure those weren't causing the problem. If you'd like more information from me, please let me know.

There is no release for shadowlands.

..yet!
