As I'm a beginner, I hadn't seen the comments of the other users, sorry.
I'm also in contact with the Resolume developers who received the reports of the different crashes and I'll also work with them to help us all to solve this problem; I hope quickly because I have a project in progress and I'm looking forward to trying the features of both tools combined.
Some other community members have mentioned the problem. We've been in contact with the Resolume developers and are working on fixing this. As mentioned in the discussion, you could roll back your version of Resolume until the fix is available.
is there any chance the move to ARM will positively impact the feature request for deploying to iOS? (perhaps Raspberry Pi as well?)
Since both use ARM processors, yes — though the majority of the work will remain to be done (user interface APIs/conventions, I/O APIs, windowing system APIs, Unix API differences, and for iOS/iPadOS the restricted runtime environment and App Store review requirements).
I am mostly worried it will negatively impact a possible port to a Windows version in the future though.
It won't be helpful toward Windows support for the majority of Windows machines, which have x86_64 processors. Unfortunately it's just something we have to do to continue supporting macOS, and it will push back the Windows version. ARM support for macOS would potentially be helpful toward ARM support for Windows, if there are enough people using Windows on ARM processors to justify doing that.
