Crash on first use

Hi all… im a newish user of Cantabile to insert plugs into Voicemeeter inserts (which works great)
However it seems that after a PC restart (or first start of day) cantabile always crashes on first startup…it seems fine after that…bizarrely…
what can I send to make tracking it down easier? I tried to attach the last crash report I can locate but as a new user I cant upload …the last thing it does is try to load waves plugins before crashing…
Thanks !
