Hello,
@1 - Have you tried Ignoring the messages if they are a nuisance to you? Adding a screenshot to the reply.
@2 - Could you disclose a _BugReport.txt and a minidump(windows user) so we could look into it? I don't think I have ever experienced this issue personally nor have I ever heard of it.
Additionally, disclosing information such as Corona version, C4D version, PC specs, OS version always helps.
Thanks!
Jan
