Please make frequent use of export project (create iwzip), one day I fear it will not re-open.

Please temporarily disable all anti-virus, malware protection, firewall and VPN - did that help?

Are you running onedrive to synv your documents to the cloud? If so, can you temporarily stop this?

In short, I am not aware of issues with WX5 stability, if you can provide evidence of a problem we would love to know (is there anything "clever" about your project or does it simply use standard WX5 code and objects??)
