AU VST2 VST3 validation crashes

I am on osx sierra 10.12.6, renoise 3.3.1 x64 installed - everything worked fine half a year ago, and now i’ve decided to check a new plugin and figured out that plugin database somehow corrupted, plugins which worked always (like TDR Kotelnikov or their EQ) wont start anymore (showing error initialization). I didnt modified my system in no way thats for sure.
So ive deleted all plugins cache files, initiated a full rescan, but now im getting hangs and crashes on many plugins which previously worked just fine, i cant do a rescan without a single crashes (mostly related to AU or VST3)… im confused a bit, checked the logic pro x - all AUs working fine…
I’ve installed the latest 3.3.2 x64 - same thing, cant validate anything, hangs, crashes, etc…
Anyone had such issues previously?

I’m on windows, so i cant help here, but did you checked the Renoise log file?

Whats the exact error message? Did you quit Renoise first and then deleted the cache? files? Do you mean the plugin database files?

You might try to rename the Renoise config dir, then start Renoise as it were new, do a scan, load the song and see. If that is not the solution, rename back the old config dir, after deleting the new one.
