It has been more than 1 month and << LogHttp: Warning: Retry 1 on https://content-service.bfda.live.use1a.on.epicgames.com/api/content/v2/artifact/4f1c2c23-2e19-4b58-b970-482936a635eb%3Apc/cooked-content >> it keeps happening to me, have you found any solution.
It slows the progress in my project 10 minutes (literally 10 minutes, it dose 8 cicles of 40 second, each one doing 4 Retry / Lockout 10s) every time I want to try any of UEFN changes, impossible to work with.
I already did the bug report.
