backend crash related to spatial profiler

[kswang1029]

This has no reliable way to reproduce the problem so please just consider this as a record until we find a reliable way. I spotted this when I use v3b2 electron app to

1. load an image
2. request a region file list

The macOS Monterey console shows

carta_backend(54323,0x70000588e000) malloc: Heap corruption detected, free list is damaged at 0x600000e481e0

Got a crash event when I was viewing multiple images with the multi-panel mode and CARTA crashed right after I created a point region.

The macOS crash report says:

I was able to reproduce this issue when working on the workspaces issue, and had to work around it by making sure spatial profiles weren't enabled until all images were loaded. Mutex issue?

I believed so but where then🤔 this is another CARTA mystery in our dev history 😆
