Urgent help needed for PM job switch

I am worried how to tackle questions around my frequent job switches. I have worked in startups and the ecosystem uncertainty has impacted me. Need some smart suggestions.

Own startup - 17 months (YC interview round)

1st startup - 1 yr - left as I wanted to move from operations towards product role

2nd startup - 1 yr 3 months - product strategy role - left coz of toxic boss

3rd startup - 10 months - product / senior program mgmt role - left coz of layoff though was a better performer (due to high pay)

Current startup - ongoing 1 yr 5 months - AI product mgmt role - want to leave coz of toxic work environment

One positive aspect is that I have been able to move from ops to product role via my switches. But will it impact my future applications?
