after effects effect has global outflags mismatch

Hey, so awhile ago I had this problem on BCC with one effect that didn't work but every other effect works just fine. I was told to update my BCC so I finally did (I used to use bcc 2019 with after effects 2021, everything worked just fine other than one effect; BCC LED) I updated to BCC 2021 to match my program but now everytime I use an effect I get this message: "after effects effect ___ has global outflags mismatch. code glags are 0 and pipl flags are 8c01488" (only one example) and it happens with every effect now.  And now all my videos have a giant red X over them when I try and add the effect? What's going on? Is it even possible to revert back to bcc 2019 because it worked better than this.
