# Steps to reproduce
I have a bigger project with a lot of xaml-files. From time to time, by trying to build the project it crashes and then it shows 103 errors and all "Buffer cannot be null"
# Expected behavior
The project should build correctly and deploy the version on the device
# Actual behavior
I get errors and have to restart and clean the project, to get it working again. Very frustating.
# Supplemental info (logs, images, videos)
We are using Xamarin.Forms.220.127.116.11
# Test environment (full version information)
Can you provide the build output, preferably diagnostic (Tools -> Options -> Build-> Log Verbosity)
Also can you post your About XS (Help -> About -> Show Details -> Copy Information)
Here is almost the same behaviour (sometime I get Buffer cannot be null with the latest XS on stable channel): https://1drv.ms/t/s!AuJWJQUKZPJoros9In9uVUYybLZylQ
The solution is to restart XS
Thank for looking into it!
Here is another one if needed: https://1drv.ms/t/s!AuJWJQUKZPJoros-PbjY18obocRP0Q
