Modern Warfare 3 Dev Error 5433 has completely broken multiplayer along with Warzone following the Season 3 Reloaded update.

Season 3 Reloaded for Call of Duty is now live and bought a wealth of new content for multiplayer, battle royale, and zombies modes. With players patiently waiting for the mid-season update to drop, many have been greeted with a frustrating error that's preventing them from loading into the action and working towards the coveted Prestige Camos.

The issue mainly impacts PlayStation players which is particularly infuriating for many wanting to load into the second half of Season 3.

Thankfully, Sledgehammer Games has already acknowledged the issue and is already looking for a fix.

Rather than waiting for the developers to apply a fix, players have already found a handy workaround to the problem enabling them to load back into matches. Within the graphics settings, changing the on-demand texture streaming to 'Small' will make the error disappear.

It's hugely frustrating to see Dev Error 5433 appear once again. The Call of Duty franchise is synonymous with game-breaking errors arriving once a new seasonal update has dropped. Despite all the rigorous testing, players continue to encounter new bugs and glitches ruining gameplay across all game modes.

Alongside the dev error, players are also reporting issues with grenade throwing and the ability to reload while sprinting. Warzone pro Ethan 'Fifakill' Pink is far from impressed.

It's unclear if the inability to reload while sprinting is an intentional change or an accidental bug that's arrived with Season 3 Reloaded. Sledgehammer Games emphasized quicker movement mechanics as one of its main selling points to promote Modern Warfare 3, suggesting the issue is a glitch.

As with most bugs and glitches, there's a high chance Sledgehammer Games and Raven Software is working on fixes for multiple issues meaning players will have to sit tight until a hotfix is applied.
