There’s a bug in 2020.42700 that causes a hard crash without any CrashAutoSave or dmp file, triggered by:
- Create a table DAT
- Right click and save to a file
- In the file parameter of that DAT, click the button to open the file browser
- Select that same file and choose Open.
If you change the Default Read Encoding to something other than Auto Detect, it works properly.
