Unload the DLL plugin show error

Hi,

we already had this error (External exception 87A) in 10.3 Rio: Hydra 6.1.95.1207 RTM: Known issues for Delphi 10.3 Rio. Seems they have fixed it in 10.3.1

possible workaround:

  • try to build your host and plugins with the Hydra_FMX_D27 run-time package, i.e. add Hydra_FMX_D27 package to VCL host. it may solve this error.
