When running Xbox One version always “Restart the Xbox” before running Fortnite don’t just use Turn off console. In many times there have been problems.
Mine is the UK MS Store and it makes me wonder if the updated versions in other countries have been updated. The 18th October 2024 update has not appeared yet its very relevant to fixing user connection problems on MS Store
What’s in Today’s Fortnite Update?
Similar problems existed on Nintendo as soon as the developers were involved with larger projects, causing crashes as quickly as UEFN connected.
The only major problem update that has occurred is making textures “Conformant Textures” in UEFN.
This means that textures must be Power of 2. Other developers think this does not affect Fortnite Creative.
In the release notes, there is an example of why this is important

The real problem lies in networking and being on Indie Dev network, if however the Xbox was on a larger network.
