I'd like to know if the pcb layout is ok for the 2 op amps that i use.I'm interested in grounding and if the op-amps have proper layout(not too long loops or poor ground planes). source files The files are all in the zip archive. You can use the easyEDA to view the gerbers or EAGLE.I used Eagle 9.3.2.

Your power supply de-coupling is still very bad. The overall bypass is still closed with 4 vias in-series (RED marked by me):
The manufacturer strongly suggests "star connection" for power bypass, and not using any ground planes around:
If you have the ground plane, the bypass traces should be connected to the plane at only ONE point (making it as a "star"). And (+) and (-) pads should have voids in the ground plane, to reduce parasitic capacitance to ground that might change feedback transfer function and cause overall instability.
