P: Crash of LrC 14.2 after selecting 'export' when inside corporate network only

Across our large scale enterprise network, we're receiving reports from users of LrC crashing when they click the 'Export' option (File -> Export).

I'm unsure what's causing this. We run a proxy on our infrastructure, and all of the necessary Adobe Endpoints have been whitelisted per this whitepaper - https://helpx.adobe.com/au/enterprise/kb/network-endpoints.html

Is there anything I'm missing here? It works for users when they take their devices home/if they hotspot. Wiresharks are not coming up with anything specific
