Created attachment 66140 --> https://bugs.winehq.org/attachment.cgi?id=66140 Wine - Thunderbird Portable - Crash - Terminal Wine Output + Builtin Crash-Report
Because working in M$ World, but using primary Ubuntu in my private Enviroment, I'm using Thunderbird Portable since many Years with Wine, and mostly no Problems so far until now.
After upgrading my german Ubuntu 18.04.3 x64 LTS System (Notebook) from WINE 4 to 5.0 RC1 by your own native PPA (https://dl.winehq.org/wine-builds/ubuntu/) suddenly Thunderbird Portable crashed immediately after starting!
Uninstalling, purging and Reinstalling of WINE DEV Version didn't help so far! (Keep in mind, everything was smooth with 4.x, until the Upgrade to 5 RC1, continuing with current RC3!)
I tested the Situation with my original old Thunderbird 58.x Portable Version, and also with an fresh from PortableApps downloaded Version 60.9 (https://portableapps.com/apps/internet/thunderbird_portable), and also with an current Version 68.3! (done on an Windows machine, upgraded the downloaded 60.9 to 68.3 without any Problem, since I can't do this in Ubuntu because of the Crash behavior! BTW, It seems the PortableApps Guys haven't upgraded their Thunderbird Version for some time?)
According to your Bug Guide I browsed through the Wine Bug list, but only old stuff appeared for Thunderbird, so here are my Terminal Wine Output, and Thunderbird's builtin Error Report Result. Additionally a screenshot from my Winecfg, not sure if this is helpful for you though.
