macOS 11 beta won't compile any project, new or existing

Greetings. After reinstalling Unreal Engine, removing all extras from the installation (iOS and Android, in my case), all projects, new or existing will not compile with the following error:

The project could not be compiled. Would you like to open it in Xcode?

clang is correct. That file doesn’t exist.

Any workaround?

Actually I have the same problem. I update my system to BigSur. Now I have Beta 2 installed. And yes, after a 30 minutes of compilation in XCode on mbp 16" I have the same problem

I have the same problem after updating to the newest beta. and also ( unsequenced modification and access to ‘CurrentMip’ [-Werror,-Wunsequenced] ) like everywhere else in the code its fine but except like 2 spots lol.

I have the same error in latest XCode in BigSur Beta 4

Me too I have the same issue with Big Sur beta 5

Same issue on Big Sur beta 6

Having same issue on 10.15.4 with Xcode 12

Fixed in 4.26 preview 2 (tested on MacOS 11, XCode 12)

For me it was fixed by upgrading to 4.26 preview 1. According to latest comments preview2 works fine too

Nice I’m going to check it out

same issue with big sur, xcode 12 and u4.26 (released)

Had the same problem on Big Sur, XCode 12.1. Both new 4.25 and 4.26 (released) projects failed to compile.

Tried it with Xcode 11.7 from:

(Apple developer account required)

still fails…
