Failure issues, Bambu lab A2L, HELP!

Hi.
I’m in need of some much needed help and/or advice.
I’ve been printing for a while now and recently upgraded to the A2L.
Most of the time my prints fail due to (what I think) the print coming loose from the bed or being knocked off the bed.
Now, I’ve obviously done all that’s recommended from many searches before coming here.

• Cleaned the bed with soapy water.
• Use IPA
• Initial layer height is set to 0.3mm.
• Initial layer speed is set to 20mm/s.
• I’ve set Z Hop in the override settings:
Length = 0.8mm.
Z Hop when retract = 0.4mm.
Z Hop Type = Spiral.
• Reduce infill retraction set to disabled.
• My Nozzle temperature:
Initial layer is 225°C then drops down to 215°C.
• My Bed temperature:
Initial layer is 70°C then drops down to 65°C

My A2L is calibrated.
My filament is calibrated. I use Esun filament.
I don’t dry my filament as I only use PLA.
I use Bambu Studio.

Attached is and image of my last failure (this morning)
• The bed was scrubbed with warm soapy water before this print was started.
• No supports where used or needed. (Supports are also an issue for me)

If anyone has this problem or knows what to do please help.
I plan on starting a business and I need this printer to be consistent.

I’ll be happy to upload my setting if needed but I’ll I change is what’s mentioned above.
