Same problem :frowning:

Same after update to 4.26 :frowning:

Hello Guys,

I had the exact same issue on my UE4.26.1 project. I solved after about 10 hours of debugging and googling. I am so happy that I decided to share with you my detailed troubleshooting procedure!
You will notice while googling that all people who have fixed this issue have found a corrupt variable or blueprint. They were able to locate it by magic or luck, then remove it to get everything fixed. This was a nice lead for me except for their last step. I am explaining in this email most details on how I fixed it:
1- I found out by “luck” that this error message shows at each new start in the Output Log. This is very useful to quickly identify the corrupt asset, otherwise, you will need to repeatedly launch packaging and wait. I am almost sure it’ll happen to your project. If I am wrong, then you are stuck with repeated packaging, sorry for you.
2- To identify the corrupt BP: close UE, move its asset to a folder outside of your project, then start again. If the same error happens again, this means this BP isn’t the corrupt one. IMPORTANT: DONT SAVE. Close UE, bring the asset back, then try with another before starting again, and so on. For me, I got it at the second try. Hint: do it from the latest added BPs.
3- If the crazy red long error message doesn’t show at the start, this means that you just identified the corrupt BP. Close again without saving. Bring it back (error message will show again), disconnect all dependencies from that BP then delete it!! This is what I’ve done to get rid of this crash, so I built that BP from scratch. It might be possible for you to try to fix it but can’t guarantee.
4- Don’t worry about the error messages for missing BPs, they will go away once the tested BP is brought back.
5- Once the starting error message is gone. Your packaging will go smoothly.

I wish this may help you as well as the UE team to answer the other posts. I also hope it’ll be made easier to debug such issues in future UE versions.

Cheers,

Searching for NoneNone in the Content folder of my project yielded the result. The problem was in the duplicated widgets, inside which the variables with links to other bluprints were duplicated (apparently unsuccessfully). Renaming variables with references to other bluprints fixed the compilation error. To check, it is enough to rename the variable and compile this bluprint - if NoneNone longer finds it in this asset, then everything is fine and the general compilation will be successful
