I’ve not had any problems using Bob’s fpPlugin with releases from 2020r1 and prior.
When I run my program with 2020r1.1 I get syntax errors with BigInteger being undefined. The plugin doesn’t show as loaded in the About Xojo window.
I have the latest version downloaded but it was from 2018. Has anyone encountered this or is it something to do with my Mac 10.15.7 setup?

Edit:
It seems it is a quarantine problem. I removed the flag as suggested by Tim Jones and it now loads.
