    I have been using UE since 4.9 and never happened to me that a hotfix breaking things, but anyway, everyone must do a backup before upgrading certain software pieces:

    - gpu driver update: backup your system drive
    - windows update: backup your system drive
    - UE new release: backup ue projects
    - UE new release updates (hotfixes): backup ue installation and ue projects

    There are several backup solutions which does incremental backups which are fast to backup and restore if anything goes wrong, you won't waste time and can be up and running after few clicks. I also do backups whenever I finish major project changes. Backups are as much important as version control software, you can't escape critical situations without any or both.

      We have VCS, and there is no problem with it, but we cant downgrade to minor version (4.25.1)... and don`t know how to solve problem right now...

      BTW: Of course the problem is appears not on only one PC, there are several configs which leads to the same crash result

          The only way at this point to have the 4.25.1 back to your system is downloading the .zip file with source and rebuild the engine, which you can download at this link (need account at GitHub and it must be linked with Epic account): https://github.com/EpicGames/UnrealEngine/releases

          Notice that it could occur that some resources inside the project that have been opened and saved with 4.25.2 might make them not able to be opened at 4.25.1 (serialization issues), so you will need to use backup of your files. Hopefully it won't happen.

          PS: You won't have it at Epic launcher and will need to get shortcuts from the executables at the compiled folders.

                    Do you mean Next time you will wait for the all clear from others before updating?

                    Anyway the update fixed the problem for me , but i'm only learning the engine at the moment.

                        It seems like the polycut tool disappears as you reach the outter edge of a mesh. Not sure if this is a bug or intentionally, but it severely limits what one can do.

                          Is there a way to downgrade to 4.25.1? Or is there a way to fix this?)
                          For those who interested. The problem was related to Virtual Textures, one of them was converted by us at previous patch in Engine Content folder, and thats why it was leading to crash after updating. Thanks everybody for the help.

                            I've downgraded to 4.25.0 because I can't package my game anymore and started using for the first time ue4 from source but each time I want to compile I get this error. Never saw this before. What could cause this error?

                              Updated to 4.25.3 and I now get a message saying. The following modules are missing or built with a different engine version for megascans. I deleted plugin and reinstalled through bridge but still get this. Any help would be huge. Thanks

                                Can the issue of World Offset Particles be fixed anytime soon.
