@ronblum I think this is related to https://github.com/rstudio/rstudio/issues/6675 and https://github.com/rstudio/rstudio/issues/7622

It seems the IDE feature of running code chunk is not taking into account the environment to evaluate the chunk option. All these issues are related to this I think.

As of Version 1.4.1103, this still does not work. Very annoying. Is there a workaround?

System details

RStudio Edition : Desktop
RStudio Version : 1.4.1103
OS Version      : macOS

Steps to reproduce the problem

1. Install an ARM (M1) build of R on macOS. This can be done by building R from source using Homebrew, or by installing r-devel from https://mac.r-project.org/.
2. Start RStudio.

Describe the problem in detail

An extremely unhelpful error appears.

dyld: could not load inserted library '/opt/homebrew/Cellar/r/4.0.3\_2/lib/R/lib/libR.dylib' because no suitable image found. Did find: /opt/homebrew/Cellar/r/4.0.3\_2/lib/R/lib/libR.dylib: mach-o, but wrong architecture /opt/homebrew/Cellar/r/4.0.3\_2/lib/R/lib/libR.dylib: stat() failed with errno=1

Describe the behavior you expected

An error message indicating what's actually wrong (architecture mismatch, trying to load ARM R into x64 RStudio session) and what to do about it (install the x64 version of R instead).

This problem is about to become much more common once R 4.1 is released with a formal ARM64 build. People who download the newest versions of R and RStudio on M1 Macs are likely to hit it.

We are still a ways off from a formal M1 build of RStudio (see https://github.com/rstudio/rstudio/issues/8652), but we don't have to implement M1 support to improve the user experience here.

If that fails too, it creates a new profile. Avoids previous uncaught exception causing MM failing to start upon borked profile. Underlying cause: creation of borked profile is unclear, but will be hard to figure out.

Closes #1084

There now have been several instances of users reporting that the MM splash screen does not show, which can be remedies by removing the profiles (from User\AppData\Local\Micro-Manager\UserProfiles). For instance, see: https://forum.image.sc/t/mm2-0-quit-and-wont-start-anymore/47293. Hopefully, loading one of these profiles running under a debugger will reveal enough of the underlying cause to decide how to prevent this from happening.

Thanks @Patrick330: you are indeed correct that the issue here is in deparse.
