To Reproduce

I cloned the complete git into _beta/interface/addons since WA is the only addon I wanted to use, so the out-of-folder files don't matter.
Then I switched to the shadowlands branch (with github desktop) and started the game. I'm at the point in the first couple of quests where I'm entering icecrown citadel.
upon entering the game thousands(!) of lua errors are contiuously happening.

Screenshots

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?
I just have WA installed

Which version of WeakAuras are you using?

Version: @Project-Version@

Are you on World of Warcraft Classic or Retail?

• Classic
• Retail
• Shadowlands Beta 9.0.1 35598 x64 Aug 17

Was it working in a previous version? If yes, which was the last good one?
I don't know, this is the first I installed @ beta

Additional Info

I didn't create any aura yet

You installed the wrong file.

ok which one is the right file?
