All FabFiltes plugins (latest release) crash in WaveLab Pro 9.5.20.
Rescan on startup and the modify in startup.ini (adding command Check64bit_Vst3=0) we suggested here does not fix the issue.
Shift plug-in processing from 64 to 32bit : no results.
I tried reinstalling without result.
WL Pro 9.5.20 (@64bit)
FabFilter total bundle (latest).
