Uh-oh ! Unable to import Site. Error 1416 (22003)

Hi everyone at Flywheel !

I’m trying to migrate a site made in Flywheel 3.3.0 into the latest public beta 5.0.6 (976) but i’m getting an error when provisionning muSQL databases (seems to be local.wp_wpgmza.sql)

I took care to rename the site and path to files when importing as Local 3.3.0 is still installed and I need to keep working on the site.

I was able to create a brand-new site in the newly installed beta, and also import another one.
I tried to re-export my site, but the export seems to be running fine. (package size is always the same)
I also tried to load it on another computer (on 5.0.6 Local) but it gives me the same exact error.
It appears that IIS is not running on my machine (service disabled), and nothing shows up in my browser under localhost:80.

Here’s a screenshot of the popup that appears near the end of the import.
.06_Error%201416%20(22003)

Here’s also the flywheel log :
local-lightning.log (149.1 KB)

I’ve been searching a solution in other topic, but nothing seems to mention my problem.
Thanks in advance for your help !
I will gladly give more info !
