Trying to deploy sp_blitzIndex - but fails

I'm trying to deploy the sp_blitzIndex procedure from Brent Ozar. I'm running it in a query window, in SSMS and get the following error: Msg 208, Level 16, State 1, Line 1 Invalid object name 'tempdb..SQLServerCheckup_2A98B846_4179_496B_AAF8_60B405E3ED68_waits'. Starting run. sp_BlitzIndex(TM) v7.99999 - December 11, 2020 This is being done on the master DB. I'm running SQL Server 2019 developer edition on my local machine. Any suggestions on a fix?
