Excel crashing and and losing hours/days of work

In my experience, Excel crashes a lot less now than in earlier versions. My routine is to not rely on autosave, nor repaired files. I turn autosave off and decide by myself when to save, and I do it by pressing F12 (save as) and append a time stamp on the file name like "Routines_220305_075.xlsx" using YYMMDD_hhm to have them the sortable by name in chronogical order.
I omit the second minute figure and thus have a new name every tenth minute.

Also happens that I append a note about the files development eg
Routines_220305_080 table of contents sheet.xlsm

The purpose is that if I want to go back to a previous version and chose another development path, I can easier chose what file to continue from.
When testing different solutions, I always do it in the original file - not a test file since it will become the origin if the test works out fine and I do not want two original named files.

Finally, I put all the passed files in a folder named like "2bdeleted in May 2022".

The main issue, having Excel not to crash?
Sorry, I do not have the solution, but F12 (and Ctrl+12 to open in fewer steps) has been very useful to both me and my customers also in other applications when the software acts like crash generators.
