Update - This issue was fixed in the 2/12/2021 Client Update:
"Updating your SQL database…" or Force An Update macro - removed all references to the previous design of the PRE table to avoid errors when running against old databases.
Known Issue - We are aware of issues with the Client update regarding the PRE table and running the "Repair Indexes and Relationships" function. The following errors are generating as of the 1/29/2021 Client update.
Programming is looking into this now. In the meantime you can click to continue running the "Repair Indexes and Relationships" function to process the rest of the tables.
