Editor Crash!!! only in editor!!! on importing assets process!!!
reopen editor can reslove ,so i dont know how to reproduce it.

i found infos above (----<・ )))><<------) are similar to the importing crash's stack trace.
maybe there is some common point between them but its sad that i dont know how to figure it out

 

reopen unity and found the prefab ,it looks good ,no missing ,not warning ,not error.

 

The file 'MemoryStream' is corrupted! Remove it and launch unity again!
[Position out of bounds!]
(Filename: C:\buildslave\unity\build\Runtime/Serialize/SerializationCaching/CachedReader.cpp Line: 214)

any ideas about what happened on line 214 of CachedReader,anyone?

 

in this case ,sometimes the script value attached to prefabs reset to default value also after i checkout or pull others commits.
such as the value turn into none of enum field
absolutely,reimport the prefab can solve
but the problem is i dont how many prefabs have issue until they print error (._.`)

 

thanks for reply ,i had make a bug report as your suggession
and our version is 2019.4.40
