Looks like it, but they still all left at once due to something that at least included strategy disagreements (from here):

In an interview, Wilde told Salon that her "final straw" came back in the spring after the primary, when, she said, she and other staffers grew tired of Buttar "challenging every decision" in "demeaning" ways that she alleged were sexist and misogynistic. Specifically, Wilde said she and her colleagues were, during the primary, focused on placing second. Then, there was concern that John Dennis, the Republican Party's candidate who faced off against Pelosi in the 2020 primary, was going to win. Wilde said she focused on traditional tactics like knocking on doors — the "basics of campaigning," she said — and that Buttar was often resistant to them. Wilde said it was "incredibly demoralizing" to hear him say that what she and other staffers continued to suggest had no impact on the election.

"He was incredibly disrespectful and hurtful, he lashed out quite a bit at everyone on the team," Wilde told Salon. Wilde said that she and other staffers outlined a list of stipulations, threatening to quit if they weren't met. Wilde says Buttar verbally agreed, but says they didn't stick. "We didn't feel it was ethical to continue taking money from donors to run a campaign that was essentially his vanity project," she added.

Wilde left, which then caused a "ripple effect." Nearly a dozen more staffers left.

Still nobody says what those disagreements were except Buttar, obliquely:

"One point of tension," Buttar said, was attending in-person events. "I built the campaign by being a very frequent face at events, any march, rally, protest, discussion, community meeting about climate change, wars, universal health care over the last three years I've been at, and I go there with people and I recruit them — that was another strategy that my staff didn't understand," he said.
