How to check the engine version for .uasset file?

I need to check the engine version of a .uasset file because when I open it in the UE Viewer it asks me to select the engine version and after selecting the version, UE Viewer crashes… 'wrong engine version’

But when selecting the engine version to 4.18 or 4.19 the file opens and on export the UE Viewer Crashes.

Just want to know how to check the correct engine version for the .uasset file so I can make sure the engine version is correctly selected and will further debug the UE Viewer.

For now I am not sure what to debug and fix the issue.

Did you ever find out the answer to this? I also would like to know.

Yes I solved this Issue my own, I automated the UE Viewer to log the engine version it was expecting while the UE Viewer was logging that the version is not correct … its mean it knows which version is correct… just log what it was expecting together with the error message.
